Kosmos 257 was operated in an orbit with a perigee of 261 kilometres (162 mi), an apogee of 396 kilometres (246 mi), 70.9 degrees of inclination, and an orbital period of 91.10 minutes.[1][4] It remained in orbit until it decayed and reentered the atmosphere on 5 March 1969.[4] It was the seventeenth of seventy nine DS-P1-Yu satellites to be launched,[1] and the sixteenth of seventy two to successfully reach orbit.[5]
