(7736) Nizhnij Novgorod is an asteroid of the central main belt , which was discovered by the Soviet astronomer Lyudmila Georgievna Karachkina on September 8, 1981 at the Crimean Observatory in Nautschnyj ( IAU code 095).
The asteroid belongs to the Eunomia family, a group named after (15) Eunomia , to which probably five percent of the asteroids in the main belt belong. The timeless (non- osculating ) orbital elements of (7736) Nizhnij Novgorod are almost identical to those of the two smaller ones, assuming the absolute magnitude of 16.1 and 16.4 compared to 12.5, asteroids (185187) 2006 SN 391 and (297979) 2002 KL 4 .
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (7736) Nizhnij Novgorod assumed a bright surface, so roughly speaking it could be be an S-asteroid .
(7736) Nizhnij Novgorod was named after the Russian city of Nizhny Novgorod on March 9, 2001 . Founded in 1221 by Yuri II , Nizhny Novgorod is now the fifth largest city in Russia .
