2311 El Leoncito
From Wikipedia, the free encyclopedia
El Leoncito orbits the Sun in the outer main-belt at a distance of 3.5–3.8 AU once every 6 years and 11 months (2,533 days). Its orbit has an eccentricity of 0.04 and an inclination of 7° with respect to the ecliptic.[1]
It has a well-observed orbit with the lowest possible uncertainty – a condition code of 0 – and an observation arc that spans over a period of almost half a century, using precovery images on photographic plates from 1972.
Physical characteristics
El Leoncito is characterized as a D-type asteroid in the Tholen taxonomy, one of only 46 known asteroids of this spectral type.[4]
The body has a low albedo of 0.04, typical for D-type asteroids.[4] Its rotation period, however, remains unknown.[1]
