Editing Andromeda (constellation) (section)

=== Meteor showers ===
Each November, the [[Andromedids]] meteor shower appears to radiate from Andromeda.{{sfn|Bakich|1995|p=60}} The shower peaks in mid-to-late November every year, but has a low peak rate of fewer than 2 meteors per hour.{{sfn|Lunsford, ''Meteor Shower List''|2012}} Astronomers have often associated the Andromedids with [[Biela's Comet]], which was destroyed in the 19th century, but that connection is disputed.{{sfn|Jenniskens|2008}} Andromedid meteors are known for being very slow and the shower itself is considered to be diffuse, as meteors can be seen coming from nearby constellations as well as from Andromeda itself.{{sfn|Lunsford, ''Activity Nov 19–23''|2011}} Andromedid meteors sometimes appear as red [[Meteoroid#Fireball|fireballs]].{{sfn|Sherrod|Koed|2003|p=58}}{{sfn|Jenniskens|Vaubaillon|2007}} The Andromedids were associated with the most spectacular meteor showers of the 19th century; the storms of 1872 and 1885 were estimated to have a peak rate of 2 meteors per second (a [[zenithal hourly rate]] of 10,000), prompting a Chinese astronomer to compare the meteors to falling rain.{{sfn|Jenniskens|2008}}{{sfn|Jenniskens|2006|p=384}} The Andromedids had another outburst on December 3–5, 2011, the most active shower since 1885, with a maximum zenithal hourly rate of 50 meteors per hour. The 2011 outburst was linked to ejecta from Comet Biela, which passed close to the Sun in 1649. None of the meteoroids observed were associated with material from the comet's 1846 disintegration. The observers of the 2011 outburst predicted outbursts in 2018, 2023, and 2036.{{sfn|Wiegert|Brown|Weryk|Wong|2012}}
