Comet P/2010 A2 is a notable body in that it displays characteristics of both asteroids and comets. It has the orbit of a main-belt asteroid and yet shows the tail of a comet.
Comet P/2010 A2 was discovered on January 1, 2010 in an image observed by G. Muler using a 0.30-m (12") Schmidt-Cassegrain telescope with a CCD camera.[1] Since it has only been observed over a 4 day period, details of the exact orbit are still poorly refined.[2] Though it appears to have come to perihelion (cloest approach to the Sun) around the end of September 2009.[2]
