Sputnik was a very simple satellite. It emitted a radio signal that was received by Russia radio observers on the ground. This pinpointed its speed, altitude, and elliptical path. Spudnik was in a very low orbit however, and after a few months it reentered the earth's atmosphere and was destroyed.
The sputnik was a satellite that produced signals so that we could receive and extract information via web and radio. So the next time we use the internet or turn on the radio, we should remember THE SPUTNIK.
It was launched into an elliptical low earth orbit.
Sputnik 1, the first man made object to orbit the earth. And we've been polluting like crazy up there ever since.
No one. It was launched into low-Earth orbit and stayed there until it fell back in the atmosphere and burned up.
Sputnik with its puppy dog passenger( Laika ) was launched in October 1957, and remained in orbit until early 1958, when it reentered EarthÂ’s atmosphere and burned up Sputnik 1 was in orbit for 3 months, completing 1440 orbits. Sputnik 2, Laika's flight, was in orbit for 162 days. There were other missions, but these two, especially Sputnik 1, were the ones to capture the world's - especially the US'- attention.
As far as we know, it didn't. But if you can launch something harmless into orbit, you can also launch something dangerous into orbit, which was a big part of the fear caused by the Sputnik launch.
Sputnik 1 was the first human-built thing that was launched into orbit and functioned while there.
Sputnik was a "family name" for a series of satellites. Some have burned up upon reentry while some were launched further out.
Sputnik was launched into a low-Earth orbit. Sputnik was launched By the Soviet Union. It was the first artificial satellite to orbit Earth. it weighed about 98 pounds and took 90 minutes to orbit earth. when Sputnik was launched the Space Race began.
It was launched into an elliptical low earth orbit.
It was in orbit around Earth.
1957
No. Sputnik 1 burned up on 4 January 1958, as it fell from orbit upon reentering Earth's atmosphere
Sputnik 1 traveled at a speed of 18000 mph, completing one orbit of the Earth every 96.2 minutes.

Sputnik was a "family name" for a series of Russian satellites. Sputnik 1 (the very first artificial satellite launched by the Russians) was in orbit in 1957, but only briefly. It was in a very low orbit, and it fell out of orbit and burned on re-entry shortly afterward, which is was designed to do. It had accomplished it's mission.
No Sputniks are still in orbit. When they were, the period of an orbit was about 88 minutes.
