no they can not orbit forever. However, the time that a satellite will remain in orbit is dependent on altitude. Satellites in orbits above about 1500 miles will never decay and fall to Earth, in the expected lifetime of the solar system.


Satellites will not stay in orbit forever. How long they stay up depends on how high they are and the satellite's ballistic coefficient, or mass/frontal area. The drag from our atmosphere decreases with height. Satellites in low orbits, say 500 km, will decay in a few years. At 1000 km they will stay up perhaps a century. Above a few thousand km they would stay practically forever.

Proper disposal of spacecraft is important. A small piece of spacecraft or debris can continue to orbit for a long time, presenting a hazard to operating spacecraft.

What are natural or artifial bodies that orbit larger celestial bodies such as planets?

These are called satellites. A lot of planets have natural satellites called moons, which are in orbit around the planet. An artificial satellite is one that is put there by man, it orbits the planet in a similar way.


Artificial satellites orbit the earth here?

Yes, artificial satellites orbit the Earth in different orbits depending on their purpose, such as communication, weather monitoring, or scientific research. These satellites are launched into space and carefully positioned to ensure stable and productive operations.
