Is sputnik still in orbit?


2 Answers

No. The Soviet satellite Sputnik 1 burned up on January 4, 1958, upon reentering Earth's atmosphere. Within the three months in space, it has completed 1440 orbits of the Earth, and travelled distance of about 70 million km (43 million mi).

The Soviet Union launched Sputnik into an elliptical low Earth orbit on 4 October 1957, orbiting for three weeks before its batteries died, then silently for two more months before falling back into the atmosphere.
