Flexi Says: Satellites that are relatively close to Earth are said to be in low Earth orbit (LEO). Satellites in LEO are often in polar orbit; they orbit over the North and South Poles, perpendicular to Earth’s spin. Because Earth rotates underneath the orbiting satellite, a satellite in polar orbit is over a different part of Earth’s surface each time it circles. Imaging satellites and weather satellites are often put in low-Earth, polar orbits.
