244 Sita is a backgroundasteroid from the inner region of theasteroid belt, approximately 11 kilometers (6.8 miles) in diameter.[1] It was discovered on 14 October 1884, by an Austrian astronomerJohann Palisa in theVienna Observatory and was named for the Hindu deitySita.[5]
This minor planet is orbiting theSun at a distance of2.17 AU with aneccentricity of 0.137 and anorbital period of 3.21 yr. Theorbital plane is tilted at an angle of 2.84° to theplane of the ecliptic.[1] It is spinning slowly, completing a rotation about its axis once every 129.056 ± 0.021 h (5.377 ± 0.001 d).[6]
