Kosmos 123 (Russian: Космос 123 meaning Cosmos 123), also known as DS-P1-Yu No.5 was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles.[1] It was built by the Yuzhnoye Design Bureau, and launched in 1966 as part of the Dnepropetrovsk Sputnik programme.[2]

A Kosmos-2I 63S1 carrier rocket was used to launch Kosmos 123.[3] The launch occurred from Site 86/1 at Kapustin Yar, at 05:31 GMT on 8 July 1966.[4]

Kosmos 123 separated from the carrier rocket into a low Earth orbit with an apogee of 490 kilometres (300 mi), a perigee of 253 kilometres (157 mi), 48.7 degrees of inclination, and an orbital period of 91.97 minutes.[2][5] It decayed from orbit on 10 December 1966.[5] Kosmos 123 was the sixth of seventy nine DS-P1-Yu satellites to be launched,[2] and the fifth of seventy two to successfully reach orbit.
