24105 Broughton, provisional designation 1999 VE10, is a background asteroid from the inner regions of the asteroid belt, approximately 3.7 kilometers (2.3 miles) in diameter. The assumed S-type asteroid was discovered on 9 November 1999, by American amateur astronomer Charles W. Juels at the Fountain Hills Observatory (678) in Arizona, United States.[1] It has a rotation period of 15.9 hours and was named after Australian amateur astronomer John Broughton.[2][3]

Orbit and classification[]

Broughton is non-family asteroid from the main belt's background population,[4][5] located near the region occupied by the Flora family, one of the largest clans of stony asteroids.[3] It orbits the Sun in the inner asteroid belt at a distance of 2.2–2.4 AU once every 3 years and 7 months (1,308 days; semi-major axis of 2.34 AU). Its orbit has an eccentricity of 0.04 and an inclination of 7° with respect to the ecliptic.[3]

The asteroid was first observed as 1997 BV6 at the Japanese Tajimi Observatory (901) in January 1997, where its observation arc begins in the following month, about 2 years prior to the asteroid's official discovery observation at Fountain Hills.[1]

Naming[]

This minor planet was named in honor of Australian amateur astronomer John Broughton (born 1952), a prolific discoverer of minor planets who received a "Shoemaker NEO Grant" in 2002.[2] The approved naming citation was published by the Minor Planet Center on 26 November 2004 (M.P.C. 53176).[8]

Physical characteristics[]

Lightcurves[]

In October 2013, a rotational lightcurve of Broughton was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 15.9442 hours with a brightness variation of 0.34 magnitude (U=2).[7]

Diameter and albedo[]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the family's largest member and namesake – and calculates a diameter of 3.65 kilometers with an absolute magnitude of 14.36.[6]
