Kosmos 105 (Russian: Космос 105 meaning Cosmos 105) or Zenit-2 No.38 was a Soviet 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[4][5] and had a mass of 4,730.0 kilograms (10,427.9 lb).[1]

Kosmos 105 was launched by a Vostok-2 rocket[6] flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 08:38 UTC on 22 January 1966,[2] 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 1945.[1]

Kosmos 105 was operated in a low Earth orbit; at an epoch of 23 January 1966 it had a perigee of 204 kilometres (127 mi), an apogee of 310 kilometres (190 mi) inclination of 65 degrees and an orbital period of 89.64 minutes.[3] On 30 January 1966, after eight days in orbit, the satellite was deorbited with its return capsule descending by parachute for recovery.[5]
