(2711) Aleksandrov is an asteroid of the main belt that was discovered on August 31, 1978 by the Russian astronomer Nikolai Stepanowitsch Tschernych at the Crimean Observatory in Nautschnyj ( IAU code 095).
In 1984 the asteroid was named after the Russian nuclear physicist Anatoly Petrovich Alexandrow (1903-1994).
The celestial body belongs to the Eos family, a group of asteroids, which typically have large semi-axes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
