1831 Nicholson, provisional designation 1968 HC, is a stony asteroid from the asteroid belt discovered on April 17, 1968 by astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland. The S-type asteroid orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 4 months.[1]
It is named after American astronomer Seth B. Nicholson (1891–1963), who pioneered in several branches of planetary research at Mount Wilson Observatory and discovered the four Jupiter moons, Sinope, Lysithea, Carme, and Ananke.[2] The lunar and Martian crater Nicholson have also been named after him.
