Kosmos 105 was launched by a Vostok-2 rocket^[4] flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 08:38 GMT on 22 January 1966,^[5] 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.^[6]

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.^[7] 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.^[8]
