Great September Comet

Astronomy
  • A long-period comet, a member of the Kreutz sungrazer group, discovered independently by many observers in the southern hemisphere in 1882 September; formerly designated 1882 II. Perihelion was on September 17 at 0.008 au (1.2 million km), when the nucleus broke into at least four fragments. At its best the comet was visible in broad daylight (magnitude at least −10), and showed a tail exceeding 20°. Its orbit is very similar to that of Ikeya–Seki (C/1965 S1), having a period of about 670 years, eccentricity 0.9999, and inclination 142°.0.
