(4992) Kálmán is an asteroid of the main middle belt , which was discovered by the Ukrainian - Soviet astronomer Lyudmyla Shuravlowa on October 25, 1982 at the Crimean Observatory in Nautschnyj ( IAU code 095).
The asteroid belongs to the Maria family, a group of asteroids named after (170) Maria . The timeless (non- osculating ) orbital elements of (4992) Kálmán are almost identical to those of the two smaller ones, assuming the absolute magnitude of 14.9 and 15.7 compared to 12.8, asteroids (77532) 2001 HA 61 and ( 172233) 2002 RB 141 .
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel in (4992) Kálmán assumed a bright surface, so it could, roughly speaking, be trade an S asteroid .
(4992) Kálmán was 15 February 1995. after the Hungarian operettas - composer Emmerich Kálmán named (1882-1953), who along with Franz Lehár and Oscar Straus as the founder of the Silver operetta applies. In 2005, the asteroid (85317) Lehár was named after Lehár .
