|Discovered by||Takao Kobayashi|
(February 27, 1997)
last perihelion: January 30–31, 1997
|Semi-major axis||8.6 AU|
|Orbital period||25.17 a|
On January 30 and January 31, 1997, Takao Kobayashi observed an object, P/1997 B1 (Kobayashi), which was initially thought to be a minor planet and was reported to the IAU as such by S. Nakano. Over the next few days, the object was observed to be in a cometary orbit. W. Offutt later showed it to be a comet. This is the first amateur CCD discovery of a comet and is also the faintest amateur discovery. It demonstrates that amateur astronomers still have an important role to play in the field of astronomical object discovery.
