5656 Oldfield, provisional designation A920 TA, is a background asteroid from the inner regions of the asteroid belt, approximately 7.7 kilometers (4.8 miles) in diameter. It was discovered on 8 October 1920, by astronomer Walter Baade at the Bergedorf Observatory in Hamburg, Germany. The asteroid was named for English musician Mike Oldfield. [1]
Oldfield is a non-family asteroid of the main belt's background population. [3] It orbits the Sun in the inner main-belt at a distance of 1.8–3.1 AU once every 3 years and 10 months (1,409 days; semi-major axis of 2.46 AU). Its orbit has an eccentricity of 0.26 and an inclination of 4° with respect to the ecliptic. [2]
The body's observation arc begins at Bergedorf two nights after its official discovery observation. [1]
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Oldfield measures 7.691 kilometers in diameter and its surface has an albedo of 0.075. [4]
As of 2018, no rotational lightcurve of Oldfield has been obtained from photometric observations. The body's rotation period, poles and shape remain unknown. [2]
This minor planet was named after English composer and multi-instrumentalist Mike Oldfield (born 1953), creator of the famed Tubular Bells albums. [1] The official naming citation was proposed by Gareth V. Williams and published by the Minor Planet Center on 25 April 1994 ( M.P.C. 23353). [5]
