452P/Sheppard-Jewitt = 2003 CC22 = 2022 B5
An asteroid, of 22nd magnitude, was discovered by a team including Scott Sheppard
and David Jewitt using the 3.6-m Canada-France- Hawaii and 2.2-m University of
Hawaii telescopes on Mauna Kea on 8 February 2003. The orbit is unusual, crossing
that of Jupiter and Saturn, both of which it can approach to within 1 au.
In October 2022 Michael Kelley reported that 2003 CC22 showed a tail in ZTF
images taken on 27 September. Sam Dean then noted that images since at least
2018 showed considerable variation in brightness.
The comet passed 0.12 au from Saturn in January 1938 and 0.50 au from Jupiter in
June 1947, with more distant passes from Saturn in September 1997 and Jupiter in
September 2002.
