Kosmos 98 (Russian: Космос 98 meaning Cosmos 98) or Zenit-2 No.31 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1965. A Zenit-2 spacecraft, Kosmos 98 was the thirty-first of eighty-one such satellites to be launched[4][5] and had a mass of 4,730 kilograms (10,430 lb).

Kosmos 98 was launched by a Vostok-2 rocket, serial number U15001-05,[6] flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 08:24 GMT on 27 November 1965 and following the satellite's successful arrival in orbit it received its Kosmos designation, along with the International Designator 1965-097A and the Satellite Catalog Number 01780.

Kosmos 98 was operated in a low Earth orbit, at an epoch of 27 November 1965, it had a perigee of 205 kilometres (127 mi), an apogee of 547 kilometres (340 mi), an inclination of 65.0° and an orbital period of 92.0 minutes. On 5 December 1965, after eight days in orbit, the satellite was deorbited with its return capsule descending by parachute for recovery by the Soviet Force.[7][5]
