(4996) Veisberg is an asteroid of the central main belt , which was discovered by the Soviet astronomer Lyudmyla Karachkina on August 11, 1986 at the Crimean Observatory in Nautschnyj ( IAU code 095). The asteroid had already been sighted at the Crimean Observatory in Nautschnyj: on October 4, 1978 under the provisional designation 1978 TJ 4 and on November 2, 1978 (1978 VJ 12 ).

The mean diameter of the asteroid was calculated to be 5.735 (± 0.191) km .

According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (4996) Veisberg assumed a bright surface, so it could, roughly speaking, be around trade an S asteroid . The rotation period of (4996) Veisberg was published in 2015 by Adam Waszczak, Chan-Kao Chang, Eran Ofek et al. examined. However, the light curve was not sufficient for a determination.

(4996) Veisberg was named on June 4, 1999 after the Russian painter Wladimir Grigorjewitsch Weisberg (1924–1985).
