(323137) 2003 BM80, provisional designation 2003 BM80 and cometary designation 282P, is an asteroid and main-belt comet from the outer regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 31 January 2003, by astronomers of the LONEOS program conducted at Anderson Mesa Station near Flagstaff, Arizona, in the United States.[2]
Orbit and classification
2003 BM80 is a main-belt comet with a Jupiter Tisserand's parameter of 2.99.[1][3] It orbits the Sun in the outer asteroid belt at a distance of 3.4–5.1 AU once every 8 years and 9 months (3,199 days; semi-major axis of 4.25 AU). Its orbit has an eccentricity of 0.19 and an inclination of 6° with respect to the ecliptic.[1]
The body's observation arc begins with its first precovery observation by the NEAT program in December 2001, more than a year prior to its official discovery observation at Anderson Mesa.[2]
Physical characteristics
Based on a generic magnitude-to-diameter conversion, 2003 BM80 measures approximately 4.4 kilometers in diameter using an absolute magnitude of 15.3 and an estimated albedo 0.07, typical for rather dark cometary-like bodies.[4]
As of 2018, no rotational lightcurve of 2003 BM80 has been obtained from photometric observations. The body's rotation period, shape and spin axis remain unknown.[1]
Numbering and naming
This minor planet was numbered by the Minor Planet Center on 6 April 2012.[5] As of 2018, it has not been named.[2]
