Do satellites move quickly. Presently circling the earth at an average altitude of 216 mi 348 km and at a speed of 17 200 mi 27 700 km per hour it completes 15 7 orbits per day and it can appear to move as fast as a. By hilman rojak april 22 2020. What do satellites do for us. On earth it s not so easy because satellites have to get up above the atmosphere and into the vacuum of space to orbit for any length of time.
So far spacex has launched 3 of its initial planned constellation of 12 000. So how do satellites stay in orbit. For example a geostationary satellite only orbits at 6 858 miles per hour. Satellites are able to orbit around the planet because they are locked into speeds that are fast enough to defeat the downward pull of gravity.
People that have caught these satellites racing across the. These two things are however very closely related because the job a satellite does usually determines both how far away from earth it needs to be how fast it has to move and the orbit it has to follow.

How many satellites are orbiting the earth in 2017 pixalytics ltd. Geodetic plate motion. Anadolu agency via getty images. How fast does a satellite move around the earth.
Satellites are sent into space by a rocket launched from the ground with enough energy at least 25 039 mph to get outside our atmosphere. We tend to group satellites either according to the jobs they do or the orbits they follow. Geodesy the science of measuring the earth s shape and positions on it allows the measurement of plate motion directly using gps the global positioning system this network of satellites is more stable than the earth s surface so when a whole continent moves somewhere at a few centimeters per year gps can tell. And satellites could conceivably be launched from cannons.
Satellites in higher orbits travel more slowly. A satellite requires a speed of 17 450 miles per hour in order to maintain a low earth orbit.
