'''11714 Mikebrown''', provisional designation ''{{mp|1998 HQ|51}}'', is a stony background asteroid from the central region of the asteroid belt, approximately {{convert|4.5|km|mi|abbr=off|sp=us}} 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.<ref name="springer" /><ref name="MPC-Mikebrown" />
== Orbit and classification == [[File:Mikebrown-2010Jan.gif|200px|thumb|left|In January 2010, ''Mikebrown'' came to opposition with Mercury, Earth, and Mars.]]
''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.<ref name="jpldata" />
On 15 May 2012, ''Mikebrown'' came within about 14.8 Gm (0.099 AU) of asteroid 625 Xenia.<ref name="Mikebrown" />
It was first observed as ''{{mp|1977 RX|8}}'' Palomar Observatory in 1977, extending the body's observation arc by 21 years prior to its official discovery observation at Anderson Mesa.<ref name="MPC-Mikebrown" />
== 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 ({{small|M.P.C. {{MoMP|11714|46104}}}}).<ref name="MPC-Circulars-Archive" />
== 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.<ref name="Masiero-2011" />
It has an absolute magnitude of 14.1.<ref name="jpldata" /> As of 2017, no rotational lightcurve of ''Mikebrown'' has been obtained from photometric observations, and the body's rotation period and shape remains unknown.<ref name="jpldata" /><ref name="lcdb" />
