Kosmos 105 (Russian: Космос 105 meaning Cosmos 105) or Zenit-2 No.38 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1966. A Zenit-2 spacecraft, Kosmos 105 was the thirty-fourth of eighty-one such satellites to be launched and had a mass of 4,730 kilograms (10,430 lb).
Kosmos 105 was launched by a Vostok-2 rocket flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 08:38 GMT on 22 January 1966, and following its successful arrival in orbit the spacecraft received its Kosmos designation, along with the International Designator 1966-003A and the Satellite Catalog Number 01945.
Kosmos 105 was operated in a low Earth orbit; at an epoch of 22 January 1966 it had a perigee of 204 kilometres (127 mi), an apogee of 310 kilometres (190 mi), an inclination of 65.0° and an orbital period of 89.7 minutes. On 30 January 1966, after eight days in orbit, the satellite was deorbited with its return capsule descending by parachute for recovery by Soviet force.
