Every object in the Universe is being attracted towards every other object by the force of gravity. Gravity keeps the International Space Station in orbit around the Earth. Gravity keeps the Moon orbiting around the Earth. Gravity keeps the Earth orbiting around the Sun.Click to see full answer. Thereof, what forces keep a satellite in orbit?That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity. Newton was the first to theorize that a projectile launched with sufficient speed would actually orbit the earth.Furthermore, does gravity do work on a satellite orbiting the Earth? A satellite in a perfectly circular orbit is moving tangentially to the earth’s surface – parallel to the ground. Gravity is pulling straight downwards, perpendicular to that orbital path. So gravity does no work. Then, how does gravity keep things in orbit? Gravity keeps objects in orbit. The centripetal force keeping one object in orbit around another object is due to the gravitational pull between the two objects. In the case of the Moon’s orbit, the centripetal force is the gravitational pull between the Moon and Earth.Do satellites run out of fuel?Satellites that have run out of fuel, do generally remain in the same orbit for years. Satellites in low earth orbit gradually burn up into the atmosphere where as higher orbit satellites remain as space junk for tens of years before they enter the atmosphere.
