It was the first artificial (manmade) object to be placed in orbit around the earth. It started the space race between the USA and the USSR.
Sputnik-1 was the first man-made object
to successfully be placed in Earth orbit.
Sputnik-1
The sputnik series of satellites were unmanned. Sputnik II carried an expendable dog.
It won't be. Sputnik reentered the atmosphere and burned up on January 4, 1958 after three months in orbit.
The second satellite to be sent into Earth orbit was "Sputnik 2".

Probably Sputnik (Sputnik 1), the Hubble (the Hubble Space Telescope) or the International Space Station (ISS) if you mean artificial satellites. Otherwise it's the moon.

Sputnik 1 Sputnik 1
the name of the first satellite is Sputnik
Sputnik 1 and Sputnik 2 were artificial satellites that traveled around the Earth. People thought that Sputnik 1 was spying on them, but all it did was transmit a simple tracking signal for 3 weeks.
The only known contents of Sputnik 1 are Electronics and some batteries.
