For an object to remain in a steady, circular orbit it must be travelling at the right speed. The diagram shows a satellite orbiting the Earth. There are three possible outcomes:

Mar 30, 2020 · Geostationary orbit (GEO) Satellites in geostationary orbit (GEO) circle Earth above the equator from west to east following Earth’s rotation – taking 23 hours 56 minutes and 4 seconds – by travelling at exactly the same rate as Earth. This makes satellites in GEO appear to be ‘stationary’ over a fixed position.
You will be able to describe the general concepts and advantages of geosynchronous orbits, polar orbits, walking orbits, Sun-synchronous orbits, and some requirements for achieving them. An illustration of orbital parameters and elements.
The Big Bang theory. Orbits. Gravity provides the force needed to maintain stable orbit of both planets around a star and also of moons and artificial satellites around a planet. Explaining...
Different orbits give satellites different vantage points for viewing Earth. This fact sheet describes the common Earth satellite orbits and some of the challenges of maintaining them.
Planets travel around the Sun in orbits that are (approximately) circular. Objects in circular orbit are travelling at a constant speed but a changing velocity. In a circular path, the direction in which the object is travelling will be constantly changing direction. A change in direction causes a change in velocity.
