Analysis of CCD photometric observations of the near-Earth asteroid (53110) 1999 AR7 made in 2015 December show it to be a binary system with a primary period of 2.7375 ± 0.0005 h and orbital period of 31.31 ± 0.02 h. The depth of the secondary mutual event indicates a minimum effective diameter ratio (Ds/Dp) of 0.41 ± 0.02.
