12838 Adamsmith, provisional designation 1997 EL55, is a stony Koronis asteroid from the outer region of the asteroid belt, approximately 6 kilometers in diameter. The asteroid was discovered on 9 March 1997, by Belgian astronomer Eric Walter Elst at ESO's La Silla Observatory in northern Chile.[6] It was named after Scottish philosopher and economist Adam Smith.[2]

Orbit and classification

Adamsmith is a member of the Koronis family, a group of co-planar, stony asteroids in the outer main-belt, named after 158 Koronis. It orbits the Sun at a distance of 2.7–3.1 AU once every 4 years and 11 months (1,789 days). Its orbit has an eccentricity of 0.07 and an inclination of 1° with respect to the ecliptic.[3]

It was first identified as 1987 DX6 at the discovering observatory in 1987, extending the asteroid's observation arc by 10 years prior to its official discovery observation.[6]
