satellite should be at least 42000Kms from center of earth .As the radius of earth is around 6370Kms ,the height reduces to 35000Kms.
for giving information to places on earth that is far far away.
The moon, at an average distance of 238,860 miles.
Artificial satellites come from all over the world. Each country send their own satellites into space.
As far as is known: -- Neither Mercury nor Venus has any natural satellites. -- Earth has one -- Mars has two
All the satellites, communications, exploratory, military etc. are artificial satellites of Earth.

Satellites in Low Earth Orbit (LEO) are typically around 160-2,000 kilometers away from the Earth's surface. Geostationary satellites, on the other hand, orbit at an altitude of about 35,786 kilometers above the equator.
Geo-stationary communication satellites are 35,768 Km far from earth surface at an equatorial latitiude.
In a sense they are continually falling to Earth, but they are so far away that the curve of their fall is big enough to follow the circumference of the Earth.
Satellites in low Earth orbit are typically around 200-2,000 kilometers (125-1,240 miles) above Earth's surface, while geostationary satellites are about 35,786 kilometers (22,236 miles) away. Other satellites can be at varying distances depending on their specific orbit and mission.
Mars has two natural satellites. Earth has one.
