Andromedid meteors

Quick Reference

A meteor shower seen in 1872, 1885, 1899, and 1904; also known as the Bielids. Activity resulted from the Earth's passage through debris from Comet Biela, which is presumed to have disintegrated in the mid-19th century. The Earth's approach to the node of the comet's orbit on 1872 November 27 was marked by a meteor storm of around 6000 meteors/h. The 1885 return was even more spectacular, with rates of perhaps 75 000 meteors/h. Gravitational perturbations have pulled the meteor stream orbit away from that of the Earth, so that few, if any, Andromedids are now seen.
