(3620) Platonov is an asteroid of the main belt that was discovered on September 7, 1981 by the Ukrainian-Soviet astronomer Lyudmila Georgievna Karachkina at the Nautschnyj branch of the Crimean Observatory ( IAU code 095) in Nautschnyj .

The asteroid belongs to the Eos family, a group of asteroids, which typically have large semiaxes 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.

(3620) Platonov was named after the Russian writer Andrei Platonowitsch Platonow (1899–1951), whose works anticipated existentialism .
