(2170) Byelorussia is an asteroid of the main inner belt that was discovered on September 16, 1971 at the Crimean Observatory in Nautschnyj ( IAU code 095). There had already been an unconfirmed sighting of the asteroid on December 14, 1949 with the provisional designation 1949 XH at the Goethe Link Observatory in Indiana .
The mean diameter of the asteroid was calculated to be 9.427 km (± 0.117). With an albedo of 0.049 (± 0.009) it has a dark surface. The rotation period of (2170) Byelorussia was established in 2015 by Adam Waszczak, Chan-Kao Chang, Eran Ofek et al. examined. However, the light curve was not sufficient for a determination.
The Italian astronomer Vincenzo Zappalà used a hierarchical cluster analysis in a publication from 1995 (et al.) To extrapolate the asteroid's membership of the Nysa family, a group of asteroids named after (44) Nysa . The group is also called the Hertha family, after (135) Hertha .
(2170) Byelorussia was named after the Belarusian Soviet Socialist Republic on April 1, 1980 . Five years later, the asteroid of the main outer belt (3012) was named Minsk after the capital of the Soviet Republic of Minsk .
