Do satellites slow down over time?

Artificial satellites slow down all the time, and uniformly, they are no longer able to resist the pull of gravity and fall back to Earth. Satellites carry fuel to help maintain their orbits, but when that fuel runs out… sooner or later they will fall back to the ground.

What happens to a satellite that is Travelling too slowly?

If the satellite is moving too slowly then the gravitational attraction will be too strong, and the satellite will fall towards the Earth. This occurs at speeds around or below 7600 m/s.

What affects the speed of a satellite?

As seen in the equation v = SQRT(G * Mcentral / R), the mass of the central body (earth) and the radius of the orbit affect orbital speed. The orbital radius is in turn dependent upon the height of the satellite above the earth.

How do you increase orbital speed?

If the force that the Sun exerts on the planet increases (as the planet moves closer), then the acceleration of the planet must increase, resulting in a higher orbital speed, and vice versa.

about 7,000 mph
