(5412) Rou is an asteroid of the main inner belt which was discovered by the Ukrainian astronomer Lyudmyla Shuravlowa on September 25, 1973 at the Crimean Observatory in Nautschnyj ( IAU code 095). There had already been sightings of the asteroid on October 6, 1931 under the provisional designation 1931 TK at the State Observatory in Heidelberg-Königstuhl .
The asteroid belongs to the Nysa group, a group of asteroids named after (44) Nysa (also called the Hertha family, after (135) Hertha ). The timeless (non- osculating ) orbital elements of (5412) Rou are almost identical to those of four smaller asteroids, assuming the absolute magnitudes of 17.4, 17.5, 17.2 and 18.2 versus 14.0 : (172514) 2003 SV 242 , (301357) 2009 CV 31 , (380735) 2005 SP 26 and 2001 KF 17 .
The mean diameter of (5412) Rou was calculated to be 4.883 (± 0.372) km and the albedo to be 0.141 (± 0.036).
The asteroid was named on May 4, 1999 after the Soviet actor and film producer Alexander Arturowitsch Rou (1906–1973), who, along with Alexander Ptuschko (1909–1973), is considered the most important director of Russian fairy tale films .
