834 Burnhamia (prov. designation: A916 SG or 1916 AD) is a large background asteroid, approximately 61 kilometers (38 miles) in diameter, that is located in the outer region of the asteroid belt. It was discovered on 20 September 1916, by German astronomer Max Wolf at the Heidelberg Observatory in southwest Germany.[1] The X-type asteroid (GS) has a rotation period of 13.9 hours. It was named after American astronomer Sherburne Wesley Burnham (1838–1921).[2]
Burnhamia 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 outer main-belt at a distance of 2.5–3.8 AU once every 5 years and 8 months (2,076 days; semi-major axis of 3.18 AU). Its orbit has an eccentricity of 0.20 and an inclination of 4° with respect to the ecliptic.[3] The asteroid's observation arc begins with its first observation as A905 UM at Heidelberg Observatory on 26 October 1905, almost 11 years prior to its official discovery observation.[1]
Naming
This minor planet was named after Sherburne Wesley Burnham (1838–1921), American astronomer who discovered many visual binary stars and is known for his Burnham Double Star Catalogue (BDS), a catalogue of double stars seen in the Northern Hemisphere, which was published in two parts by the Carnegie Institution of Washington in 1906. Burnham observed from the Chicago (1877), Lick (1888) and Yerkes (1897) observatories. The naming was published in the journal Astronomische Nachrichten in 1921 (AN 214, 69), and was also mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 82).[2] The lunar crater Burnham is also named in his honor.[12]
