Storms do not only occur on Earth; other planetary bodies with a sufficient atmosphere ([[giant planet]]s in particular) also undergo stormy weather. The [[Great Red Spot]] on [[Jupiter]] provides a well-known example.<ref>{{cite news |last1=JoAnna |first1=Wendel |title=Jupiter's Great Red Spot: Our Solar System's Most Famous Storm |url=https://www.space.com/jupiter-great-red-spot.html |access-date=16 January 2021 |work=Space.com |agency=Space.com contributor |date=October 2019 |language=en}}</ref> Though technically an anticyclone, with greater than hurricane wind speeds, it is larger than the Earth and has persisted for at least 340 years, having first been observed by astronomer [[Giovanni Domenico Cassini]]. [[Neptune]] also had its own lesser-known [[Great Dark Spot]].

In September 1994, the [[Hubble Space Telescope]] – using [[Wide Field Planetary Camera 2]] – imaged storms on [[Saturn]] generated by upwelling of warmer air, similar to a terrestrial thunderhead. The east–west extent of the same-year{{clarify|date=September 2015}} storm equaled the diameter of Earth<ref>{{Cite web |last=information@eso.org |title=ESA/Hubble Space Telescope |url=https://esahubble.org/ |access-date=2022-10-25 |website=esahubble.org |language=en}}</ref>{{Failed verification|date=October 2022}}. The storm was observed earlier in September 1990 and acquired the name [[Dragon Storm (astronomy)|Dragon Storm]].

The dust storms of [[Mars]] vary in size, but can often cover the entire planet. They tend to occur when Mars comes closest to the Sun, and have been shown to increase the global temperature.<ref>{{cite web|last=Philips|first=Tony|date=16 July 2001|title=Planet Gobbling Dust Storms|work=NASA Science News|access-date=2006-06-07|url=https://science.nasa.gov/science-news/science-at-nasa/2001/ast16jul_1/|archive-date=26 May 2010|archive-url=https://web.archive.org/web/20100526230133/http://science.nasa.gov/science-news/science-at-nasa/2001/ast16jul_1/|url-status=dead}}</ref>

One particularly large Martian storm was exhaustively studied up close due to coincidental timing. When the first [[spacecraft]] to successfully orbit another planet, [[Mariner 9]], arrived and successfully orbited Mars on 14 November 1971, [[Planetary science|planetary scientists]] were surprised to find the [[celestial body's atmosphere|atmosphere]] was thick with a planet-wide robe of [[dust]], the largest storm ever observed on Mars. The surface of the planet was totally obscured. Mariner 9's computer was reprogrammed from Earth to delay imaging of the surface for a couple of months until the dust settled, however, the surface-obscured images contributed much to the collection of Mars atmospheric and planetary surface science.<ref name=Pyle2012-M9>{{cite book |last=Pyle|first=Rod |title=Destination Mars |year=2012 |publisher=Prometheus Books |isbn=978-1-61614-589-7 |pages=73–78}}</ref>

Two [[extrasolar planet]]s are known to have storms: [[HD 209458 b]]<ref>{{cite news |last=Rincon |first=Paul |title='Superstorm' rages on exoplanet |work=[[BBC News]] London |date=23 June 2010 }}</ref> and [[HD 80606 b]]. The former's storm was discovered on 23 June 2010, and measured at {{convert|6200|km/h|abbr=on}}, while the latter produces winds of {{convert|17700|km/h|abbr=on}} across the surface. The spin of the planet then creates giant swirling shock-wave storms that carry the heat aloft.<ref>{{cite web|last1=Boyle|first1=Alan|title=10 Types Of Alien Weather That Put Earth To Shame|url=http://listverse.com/2014/06/16/10-types-of-alien-weather-that-put-earth-to-shame/|website=Listverse|access-date=2014-06-16|date=16 June 2014}}</ref>
