A '''meteor shower''' is a celestial event in which a number of [[meteor]]s are observed to radiate, or originate, from one point in the [[night sky]]. These meteors are caused by streams of cosmic debris called [[meteoroid]]s entering [[Earth's atmosphere]] at extremely high speeds on parallel trajectories. Most meteors are smaller than a grain of sand, so almost all of them disintegrate and never hit the Earth's surface. Very intense or unusual meteor showers are known as '''meteor outbursts''' and '''meteor storms''', which produce at least 1,000 meteors an hour, most notably from the [[Leonids]].<ref name="MeteorShowers">{{Cite book |last=Jenniskens |first=P. |title=Meteor Showers and their Parent Comets |date=2006 |publisher=Cambridge University Press |isbn=978-0-521-85349-1}}</ref> The Meteor Data Centre lists over 900 suspected meteor showers of which about 100 are well established.<ref>[http://www.ta3.sk/IAUC22DB/MDC2007/Roje/roje_lista.php Meteor Data Center list of Meteor Showers]</ref> Several organizations point to viewing opportunities on the Internet.<ref>St. Fleur, Nicholas, [https://www.nytimes.com/interactive/2018/science/meteor-showers-2018.html?smid=spacecal "The Quadrantids and Other Meteor Showers That Will Light Up Night Skies in 2018]", ''The New York Times'', January 2, 2018</ref> NASA maintains a daily map of active meteor showers.<ref>[http://cams.seti.org/FDL/ NASA Meteor Shower Portal]</ref>

In the modern era, the first great meteor storm was the [[Leonids]] of November 1833. One estimate is a peak rate of over one hundred thousand meteors an hour,<ref>[http://www.space.com/scienceastronomy/astronomy/leonids_1833_011114.html Space.com] The 1833 Leonid Meteor Shower: A Frightening Flurry</ref> but another, done as the storm abated, estimated more than two hundred thousand meteors during the 9 hours of the storm,<ref name="MAC">[http://leonid.arc.nasa.gov/history.html Leonid MAC] Brief history of the Leonid shower</ref> over the entire region of [[North America]] east of the [[Rocky Mountains]].

The actual nature of meteors was still debated during the 19th century. Meteors were conceived as an atmospheric phenomenon by many scientists ([[Alexander von Humboldt]], [[Adolphe Quetelet]], [[Johann Friedrich Julius Schmidt|Julius Schmidt]]) until the Italian astronomer [[Giovanni Schiaparelli]] ascertained the relation between meteors and comets in his work  ''"Notes upon the astronomical theory of the falling stars" ([[1867]]).'' In the 1890s, Irish astronomer [[George Johnstone Stoney]] (1826–1911) and British astronomer [[Arthur Matthew Weld Downing]] (1850–1917) were the first to attempt to calculate the position of the dust at Earth's orbit. They studied the dust ejected in 1866 by comet [[55P/Tempel-Tuttle]] before the anticipated Leonid shower return of 1898 and 1899. Meteor storms were expected, but the final calculations showed that most of the dust would be far inside Earth's orbit. The same results were independently arrived at by [[Adolf Berberich]] of the [[Königliches Astronomisches Rechen Institut]] (Royal Astronomical Computation Institute) in Berlin, Germany. Although the absence of meteor storms that season confirmed the calculations, the advance of much better computing tools was needed to arrive at reliable predictions.

In 1981, Donald K. Yeomans of the [[Jet Propulsion Laboratory]] reviewed the history of meteor showers for the Leonids and the history of the dynamic orbit of Comet Tempel-Tuttle.<ref>{{Cite journal |last=Yeomans |first=Donald K. |date=September 1981 |title=Comet Tempel-Tuttle and the Leonid meteors |journal=[[Icarus (journal)|Icarus]] |volume=47 |issue=3 |pages=492–499 |bibcode=1981Icar...47..492Y |doi=10.1016/0019-1035(81)90198-6}}</ref> A graph<ref>[https://web.archive.org/web/20061123062359/http://www.iltrails.org/leokin4.gif https://web.archive.org]</ref> from it was adapted and re-published in ''[[Sky and Telescope]]''.<ref>[http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/19339/1/98-0663.pdf Comet 55P/Tempel-Tuttle and the Leonid Meteors] {{webarchive|url=https://web.archive.org/web/20070630230010/http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/19339/1/98-0663.pdf |date=2007-06-30 }}(1996, see p.&nbsp;6)</ref> It showed relative positions of the Earth and Tempel-Tuttle and marks where Earth encountered dense dust. This showed that the meteoroids are mostly behind and outside the path of the comet, but paths of the Earth through the cloud of particles resulting in powerful storms were very near paths of nearly no activity.

In 1985, E. D. Kondrat'eva and E. A. Reznikov of Kazan State University first correctly identified the years when dust was released which was responsible for several past Leonid meteor storms. In 1995, [[Peter Jenniskens]] predicted the 1995 [[Alpha Monocerotids]] outburst from dust trails.<ref>Article published in 1997, notes prediction in 1995 - {{Cite journal |last1=Jenniskens |first1=P. |last2=Betlem |first2=H. |last3=De Lignie |first3=M. |last4=Langbroek |first4=M. |date=1997 |title=The Detection of a Dust Trail in the Orbit of an Earth-threatening Long-Period Comet |journal=Astrophysical Journal |volume=479 |issue=1 |pages=441 |bibcode=1997ApJ...479..441J |doi=10.1086/303853 |doi-access=free}}</ref> In anticipation of the 1999 Leonid storm, [[Robert H.

==Radiant point ==
{{main|Radiant (meteor shower)}}
[[File:PSM V18 D201 Shower of perseids sept 6 and 7.jpg|thumb|right|Meteor shower on chart]]

Because meteor shower particles are all traveling in parallel paths and at the same velocity, they will appear to an observer below to radiate away from a single point in the sky. This [[radiant (meteor shower)|radiant]] point is caused by the effect of [[Perspective (graphical)|perspective]], similar to parallel railroad tracks converging at a single vanishing point on the horizon. Meteor showers are normally named after the constellation from which the meteors appear to originate. This "fixed point" slowly moves across the sky during the night <!-- course of the shower --> due to the Earth turning on its axis, the same reason the stars appear to slowly march across the sky. The radiant also moves slightly from night to night against the background stars (radiant drift) due to the Earth moving in its orbit around the Sun. See [http://www.imo.net/calendar/2017 ''IMO'' Meteor Shower Calendar 2017] ([[International Meteor Organization]]) for maps of drifting "fixed points".

When the moving radiant is at the highest point, it will reach the observer's sky that night. The Sun will be just clearing the eastern horizon. For this reason, the best viewing time for a meteor shower is generally slightly before dawn — a compromise between the maximum number of meteors available for viewing and the brightening sky, which makes them harder to see.

==Naming ==
Meteor showers are named after the nearest constellation, or bright star with a Greek or Roman letter assigned that is close to the radiant position at the peak of the shower, whereby the grammatical [[declension]] of the Latin [[possessive form]] is replaced by "id" or "ids." Hence, meteors radiating from near the star [[Delta Aquarii]] (declension "-i") are called the [[Delta Aquariids]]. The International Astronomical Union's Task Group on Meteor Shower Nomenclature and the IAU's Meteor Data Center keep track of meteor shower nomenclature and which showers are established.

==Origin of meteoroid streams ==
[[File:Ssc2005-04a medium.jpg|thumb|[[Comet Encke]]'s meteoroid trail is the diagonal red glow.]]
[[File:Sig06-011 medium.jpg|thumb|Meteoroid trail between fragments of [[Comet 73P]]]]

A meteor shower results from an interaction between a planet, such as Earth, and streams of debris from a [[comet]] (or occasionally an [[asteroid]]). Comets can produce debris by water vapor drag, as demonstrated by [[Fred Whipple]] in 1951,<ref>{{Cite journal |last=Whipple |first=F. L. |year=1951 |title=A Comet Model. II. Physical Relations for Comets and Meteors |journal=Astrophys. J. |volume=113 |page=464 |bibcode=1951ApJ...113..464W |doi=10.1086/145416|doi-access=free }}</ref> and by breakup. Whipple envisioned comets as "dirty snowballs", made up of rock embedded in ice, orbiting the [[Sun]]. The "ice" may be [[water]], [[methane]], [[ammonia]], or other [[Volatile (astrogeology)|volatiles]], alone or in combination. The "rock" may vary in size from a dust mote to a small boulder. Dust mote sized solids are [[orders of magnitude]] more common than those the size of sand grains, which, in turn, are similarly more common than those the size of pebbles, and so on. When the ice warms and sublimates, the vapor can drag along dust, sand, and pebbles.

Each time a comet swings by the Sun in its [[orbit]], some of its ice vaporizes, and a certain number of meteoroids will be shed. The meteoroids spread out along the entire trajectory of the comet to form a meteoroid stream, also known as a "dust trail" (as opposed to a comet's "gas tail" caused by the tiny particles that are quickly blown away by solar radiation pressure).

Recently, [[Peter Jenniskens]]<ref name="Jenniskens P. 2006">Jenniskens P. (2006). ''Meteor Showers and their Parent Comets''. Cambridge University Press, Cambridge, U.K., 790 pp.</ref> has argued that most of our short-period meteor showers are not from the normal water vapor drag of active comets, but the product of infrequent disintegrations, when large chunks break off a mostly dormant comet. Examples are the [[Quadrantids]] and [[Geminids]], which originated from a breakup of asteroid-looking objects, {{mpl|196256|2003 EH|1}} and [[3200 Phaethon]], respectively, about 500 and 1000 years ago. The fragments tend to fall apart quickly into dust, sand, and pebbles and spread out along the comet's orbit to form a dense meteoroid stream, which subsequently evolves into Earth's path.

==Dynamical evolution of meteoroid streams ==

Shortly after Whipple predicted that dust particles traveled at low speeds relative to the comet, Milos Plavec was the first to offer the idea of a ''dust trail'', when he calculated how meteoroids, once freed from the comet, would drift mostly in front of or behind the comet after completing one orbit. The effect is simple [[celestial mechanics]]&nbsp;– the material drifts only a little laterally away from the comet while drifting ahead or behind the comet because some particles make a wider orbit than others.<ref name="Jenniskens P. 2006" /> These dust trails are sometimes observed in comet images taken at mid infrared wavelengths (heat radiation), where dust particles from the previous return to the Sun are spread along the orbit of the comet (see figures).

The gravitational pull of the planets determines where the dust trail would pass by Earth orbit, much like a gardener directing a hose to water a distant plant. Most years, those trails would miss the Earth altogether, but in some years, the Earth is showered by meteors. This effect was first demonstrated from observations of the 1995 [[alpha Monocerotids]],<ref>Jenniskens P., 1997. Meteor steram activity IV. Meteor outbursts and the reflex motion of the Sun. Astron. Astrophys. 317, 953–961.</ref><ref>Jenniskens P., Betlem, H., De Lignie, M., Langbroek, M. (1997). The detection of a dust trail in the orbit of an Earth-threatening long-period comet. Astrohys. J. 479, 441–447.</ref> and from earlier not widely known identifications of past Earth storms.

Over more extended periods, the dust trails can evolve in complicated ways. For example, the orbits of some repeating comets, and meteoroids leaving them, are in [[resonant orbits]] with [[Jupiter]] or one of the other large planets&nbsp;– so many revolutions of one will equal another number of the other. This creates a shower component called a filament.

A second effect is a close encounter with a planet. When the meteoroids pass by Earth, some are accelerated (making wider orbits around the Sun), others are decelerated (making shorter orbits), resulting in gaps in the dust trail in the next return (like opening a curtain, with grains piling up at the beginning and end of the gap).  Also, Jupiter's perturbation can dramatically change sections of the dust trail, especially for a short period comets, when the grains approach the giant planet at their furthest point along the orbit around the Sun, moving most slowly. As a result, the trail has a ''clumping'', a ''braiding'' or a ''tangling'' of ''crescents'', of each release of material.

The third effect is that of [[radiation pressure]] which will push less massive particles into orbits further from the Sun&nbsp;– while more massive objects (responsible for [[bolide]]s or [[Glowworm (astronomy)|fireball]]s) will tend to be affected less by radiation pressure. This makes some dust trail encounters rich in bright meteors, others rich in faint meteors.
Over time, these effects disperse the meteoroids and create a broader stream. The meteors we see from these streams are part of ''annual showers'', because Earth encounters those streams every year at much the same rate.

When the meteoroids collide with other meteoroids in the [[Zodiacal dust|zodiacal cloud]], they lose their stream association and become part of the "sporadic meteors" background. Long since dispersed from any stream or trail, they form isolated meteors, not a part of any shower. These random meteors will not appear to come from the radiant of the leading shower.

== Famous meteor showers ==

=== Perseids and Leonids ===

In most years, the most visible meteor shower is the [[Perseids]], which peak on 12 August of each year at over one meteor per minute. NASA has a [http://leonid.arc.nasa.gov/estimator.html tool] to calculate how many meteors per hour are visible from one's observing location.

The [[Leonids|Leonid]] meteor shower peaks around 17 November of each year. The Leonid shower produces a meteor storm, peaking at rates of thousands of meteors per hour. Leonid storms gave birth to the term ''meteor shower'' when it was first realised that, during the November 1833 storm, the meteors radiated from near the star Gamma Leonis. The last Leonid storms were in 1999, 2001 (two), and 2002 (two). Before that, there were storms in 1767, 1799, 1833, 1866, 1867, and 1966. When the Leonid shower is not ''storming'', it is less active than the Perseids.

Any other [[Solar System]] body with a reasonably transparent atmosphere can also have meteor showers.  As the Moon is in the neighborhood of Earth it can experience the same showers, but will have its own phenomena due to its lack of an atmosphere ''per se'', such as vastly increasing its [[sodium tail of the Moon|sodium tail]].<ref>{{Cite journal |last=Hunten |first=D.

Many planets and moons have impact craters dating back large spans of time. But new craters, perhaps even related to meteor showers are possible. Mars, and thus its moons, is known to have meteor showers.<ref>{{Cite web |title=Meteor showers at Mars |url=http://www.arm.ac.uk/~aac/meteors_on_mars.html |url-status=dead |archive-url=https://web.archive.org/web/20070724073904/http://www.arm.ac.uk/~aac/meteors_on_mars.html |archive-date=2007-07-24 |access-date=2007-11-26}}</ref> These have not been observed on other planets as yet but may be presumed to exist. For Mars in particular, although these are different from the ones seen on Earth because of the different orbits of Mars and Earth relative to the orbits of comets. The Martian atmosphere has less than one percent of the density of Earth's at ground level, at their upper edges, where meteoroids strike; the two are more similar. Because of the similar air pressure at altitudes for meteors, the effects are much the same. Only the relatively slower motion of the meteoroids due to increased distance from the sun should marginally decrease meteor brightness. This is somewhat balanced because the slower descent means that Martian meteors have more time to ablate.<ref>{{Cite web |title=Can Meteors Exist at Mars? |url=http://star.arm.ac.uk/~aac/atmos2.jpg |url-status=dead |archive-url=https://web.archive.org/web/20170701055010/http://star.arm.ac.uk/~aac/atmos2.jpg |archive-date=2017-07-01 |access-date=2006-12-30}}</ref>

On March 7, 2004, the panoramic camera on [[Mars Exploration Rover]] ''[[Spirit (rover)|Spirit]]'' recorded a streak which is now believed to have been caused by a meteor from a Martian meteor shower associated with comet [[114P/Wiseman-Skiff]].  A strong display from this shower was expected on December 20, 2007. Other showers speculated about are a "Lambda Geminid" shower associated with the [[Eta Aquariids]] of Earth (''i.e.'', both associated with [[Halley's Comet|Comet 1P/Halley]]), a "Beta Canis Major" shower associated with [[Comet 13P/Olbers]], and "Draconids" from [[5335 Damocles]].<ref>{{Cite web |title=Meteor Showers and their Parent Bodies |url=http://star.arm.ac.uk/~aac/showers.jpg |url-status=dead |archive-url=https://web.archive.org/web/20081003155932/http://star.arm.ac.uk/~aac/showers.jpg |archive-date=2008-10-03 |access-date=2006-12-30}}</ref>

Isolated massive impacts have been observed at Jupiter: The 1994 [[Comet Shoemaker–Levy 9]] which formed a brief trail as well, and successive events since then (see [[List of Jupiter events#Impact|List of Jupiter events]].)
