Every now and then you may see news of satellites (卫星) sent into space. On Feb 21, for example, US company SpaceX took 46 satellites into orbit (轨道). On Feb 27, China sent 22 satellites into space. Why do we need ...
A low Earth orbit (LEO) satellite system uses a large fleet of satellites, each in a circular orbit at a constant altitude of a few hundred miles. The orbits take the satellites over, or nearly over, the geographic poles. Each revolution takes from 90 minutes to a few hours. The fleet ...

Satellite internet uses a network of satellites that orbit the Earth in space. The satellites are typically positioned in geostationary orbit, which means they remain in a fixed position relative to the Earth’s surface, about 22,000 miles above the Equator. The system involves three main compone...

Orbit is when an object orbits around another object in space, such as satellites orbits around the earth. This is achieved by moving fast enough so that instead of falling back to earth, it falls around the earth.Answer and Explanation: ...

A geosynchronous orbit is a special position high above the Earth that allows an object to keep pace with the rotation our planet. In circular geosynchronous orbits, satellites are in a "sweet spot" in which they stay in the same location by longitude but may drift to the north and south,...
Artificial satellites are man-made celestial objects that are launched into orbit. The first satellite, Sputnik I, was launched into space in 1957 by the Soviet Union. Since then, hundreds of satellites, like the Terra satellite, have orbited Earth providing valuable information to scientists. ...
The exosphere is also the region where some satellites orbit, particularly those designed for long-term observations of Earth or communications. The low density of particles in this layer means that there is minimal drag on these satellites, allowing them to maintain their orbits for extended period...
