244 Sita is a background asteroid from the inner region of the asteroid belt, approximately 11 kilometers (6.8 miles) in diameter.[1] It was discovered on 14 October 1884, by an Austrian astronomer Johann Palisa in the Vienna Observatory and was named for the Hindu deity Sita.[5]
This minor planet is orbiting the Sun at a distance of 2.17 AU with an eccentricity of 0.137 and an orbital period of 3.21 yr. The orbital plane is tilted at an angle of 2.84° to the plane 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]
