WebSep 27, 2024 · A satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it. A satellite orbiting closer to the Earth requires more velocity to resist the stronger gravitational pull. At 384,403 kilometers from the center of the Earth, the Moon completes a single orbit in 28 days. The higher a satellite’s orbit, the slower it moves. Certain orbital altitudes have special properties, like a geosynchronous orbit, in which a satellite travels around the Earth exactly once each day. See more Just as different seats in a theater provide different perspectives on a performance, different Earth orbits give satellites varying perspectives, each … See more There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface. … See more Together, the satellites height, eccentricity, and inclination determine the satellites path and what view it will have of Earth. See more Changing a satellites height will also change its orbital speed. This introduces a strange paradox. If a satellite operator wants to increase the … See more

"In spaceflight, an orbital maneuver (otherwise known as a burn) is the use of propulsion systems to change the orbit of a spacecraft. For spacecraft far from Earth (for example those in orbits around the Sun) an orbital maneuver is called a deep-space maneuver (DSM). The rest of the flight, especially in a transfer orbit, is called coasting. " - Earth's changing orbit
