First was sputnik, but anything from the Direct TV and XM radio satellites and telecommunication, GPS to the International Space Station are artificial satellites in Earth Orbit. There are artificial satellites currently in orbit around other planets as well.

yes
Low earth orbit (LEO) satellites are defined as any artificial object between 160 km and 2000 km altitude. Any satellite from 160 km to 690km are in the Thermosphere.Any satellite in the region between 690km to 10,000 kmaltitude are in the Exosphere.10,000 km is considered the very top of the atmosphere. Any satellites above this altitude is not considered in the atmosphere. Geostationary satellites for example are at an altitude of 35,786 km.
Thermosphere and the exosphere
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.
Satellites in a low orbit, however, are slowed by friction with Earth's atmosphere.
They are launched by rockets.

If they are in the atmosphere (low earth orbit), satellites are in the ionosphere. If they are in higher orbits, satellites are considered to be outside the atmosphere.

Yes, but there are also some that orbit other planets.

Bodies that orbit planets or moons are called satellites.
