(5570) Kirsan is an asteroid of the main outer belt that was discovered by the Soviet astronomer Nikolai Tschernych on April 4, 1976 at the Crimean Observatory in Nautschnyj ( IAU code 095).
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (5570) Kirsan assumed a dark surface, so it could, roughly speaking, be around trade a C asteroid .
(5570) Kirsan was named on June 20, 1997 after the politician and chess official Kirsan Nikolajewitsch Ilyumschinow , who has been President of the World Chess Federation FIDE since 1995 . In the dedication to the International Astronomical Union , Ilyumschinov is incorrectly described as a chess grandmaster and it is reminded of his election for the second term in 1996.
