11714 Mikebrown, provisional designation Template:Mp, is a stony background asteroid from the central region of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 28 April 1998, by astronomers of the Lowell Observatory Near-Earth Object Search (LONEOS) at the U.S. Anderson Mesa Station near Flagstaff, Arizona, and later named after American astronomer Michael Brown.[1][2]
Orbit and classification
Mikebrown is a non-family asteroid from the main belt's background population. It orbits the Sun in the central main-belt at a distance of 2.0–3.4 AU once every 4 years and 4 months (1,596 days). Its orbit has an eccentricity of 0.26 and an inclination of 3° with respect to the ecliptic.[3]
On 15 May 2012, Mikebrown came within about 14.8 Gm (0.099 AU) of asteroid 625 Xenia.[4]
It was first observed as Template:Mp Palomar Observatory in 1977, extending the body's observation arc by 21 years prior to its official discovery observation at Anderson Mesa.[2]
Naming
This minor planet was named after American astronomer Michael E. Brown (born 1965), a professor of astronomy at Caltech in California, and best known for his discoveries of trans-Neptunian objects, in particular the dwarf planet 136199 Eris. The official naming citation was published on 24 July 2002 (M.P.C. Template:MoMPScript error: No such module "Check for unknown parameters".).[5]
Physical characteristics
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Mikebrown measures 4.451 kilometers in diameter and its surface has an albedo of 0.246, which is typical for stony S-type asteroids.[6]
It has an absolute magnitude of 14.1.[3] As of 2017, no rotational lightcurve of Mikebrown has been obtained from photometric observations, and the body's rotation period and shape remains unknown.[3][7]
