Biela's Comet

Biela's Comet

      short-period comet discovered (1826) by and named for the Austrian astronomer Wilhelm, Baron von Biela (Biela, Wilhelm, Freiherr von) (1782–1856). It was identified by Biela as a periodic comet that returned every 6.6 years.

      Biela's Comet underwent remarkable transformations; it was observed in 1846 to break in two, and in 1852 the fragments returned as twin comets that were never seen thereafter. In 1872 and 1885, however, when Earth crossed the path of the comet's known orbit, bright meteor showers (known as Andromedids, or Bielids) were observed, lending strength to astronomers' deduction that all meteor showers are composed of fragments of disintegrated comets.
