11714 Mikebrown (1998 HQ51) is a main-belt asteroid discovered by Lowell Observatory. It is named after the astronomer Michael E. Brown.
Mikebrown is unusually eccentric and not very bright.[1] With an absolute magnitude (H) of only 13.9,[1] it is likely less than 10 kilometres (6.2 mi) in diameter.[2]
Astronomers have not noticed any outbursts by Mikebrown.
On May 15, 2012, Mikebrown came within about 14.8 Gm (0.099 AU) of 625 Xenia.[3]
