Kosmos 497 was placed into a low Earth orbit with a perigee of, an apogee of, 70.9 degrees of inclination, and an orbital period of 95.2 minutes.[1] It decayed from orbit on 7 November 1973.[4]
Kosmos 497 was the twelfth of nineteen DS-P1-I satellites to be launched.[1] Of these, all reached orbit successfully except the seventh.[5]
