5641 McCleese, provisional designation 1990 DJ, is a rare-type Hungaria
Mars-crosser from the innermost regions of the asteroid belt
, approximately 4 kilometers in diameter.
It was discovered on 27 February 1990, by American astronomer
Classification and orbit
McCleese is classified as a bright and rare
perihelion of 1.589 AU
, McCleese also crosses the orbit of Mars.
The asteroid orbits the Sun in the innermost main-belt at a distance of 1.6–2.0 AU once every 2 years and 5 months (896 days). Its orbit has an eccentricity of 0.13 and an inclination of 22° with respect to the ecliptic.[1] In 1973, it was first identified as 1973 GA at Lick Observatory, extending the body's observation arc by 17 years prior to its official discovery observation at Palomar.[3]
Lightcurve
Photometric observations of McCleese by
U=2).[9] With a period of 418 hours, the body is one of the Top 100 slow rotators
known to exist.
Diameter estimates
According to the surveys carried out by the Infrared Astronomical Satellite
albedo of 0.455 and 0.34, respectively.[5][6] In agreement with WISE, the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.3 and derives a diameter of 3.67 kilometers using an absolute magnitude of 14.1.[4]
