It was built by the Yuzhnoye Design Bureau, and launched in 1969 as part of the Dnepropetrovsk Sputnik programme.[1] It had a mass of {{convert|325|kg|lb|abbr=on}}.[1] Kosmos 265 was launched from Plesetsk Cosmodrome Site 133/1,[2] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 7 February 1969 at 13:59 UTC, and resulted in Kosmos 265's successful deployment into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1969-012A. Kosmos 265 was operated in an orbit with a perigee of {{convert|261|km}}, an apogee of {{convert|413|km}}, 70.9 degrees of inclination, and an orbital period of 91.3 minutes.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 1 May 1969.[4] It was the eighteenth of seventy nine DS-P1-Yu satellites to be launched,[1] and the seventeenth of seventy two to successfully reach orbit.[5] {{-}}See also{{Portal|Spaceflight}}
