941 Murray (prov. designation: A920 TF or 1920 HV) is a background asteroid, approximately 18 kilometers (11 miles) in diameter, located in the central region of the asteroid belt. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 10 October 1920.[1] The X-type asteroid has a short rotation period of 3.4 hours. It was named after British professor Gilbert Murray (1866–1957).[2]
Murray is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.[4][5] It orbits the Sun in the central asteroid belt at a distance of 2.2–3.3 AU once every 4 years and 8 months (1,695 days; semi-major axis of 2.78 AU). Its orbit has an eccentricity of 0.20 and an inclination of 7° with respect to the ecliptic.[3] The body's observation arc begins at Vienna Observatory on 11 October 1920, the night after its official discovery observation.[1]
Naming
This minor planet was named after Gilbert Murray (1866–1957), British classical scholar and diplomat who helped post-war Austria in 1920 through the League of Nations. The naming was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 91).[2]
