What is "andromedids"

The Andromedids meteor shower is associated with Biela's Comet, the showers occurring as Earth passes through old streams left by the comet's tail. The comet was observed to have broken up by 1846; further drift of the pieces by 1852 suggested the moment of breakup was in either 1842 or early 1843, when the comet was near Jupiter. The breakup led to particularly spectacular showers in subsequent cycles (particularly in 1872 and 1885).

In the early 19th century, before the break-up of comet 3D/Biela, the radiant was in Cassiopeia. In the last century the radiant of the modern weaker meteor shower is generally in the constellation of Andromeda as the name of the shower suggests, but due to its age and diffuseness meteors may appear to come from the neighbouring constellations, such as Pisces, Triangulum and Cassiopeia.
