Nota: be careful not to confuse the synchronous orbit of a satellite with a satellite synchronous rotation. A Sun-synchronous orbit (sometimes called a heliosynchronous orbit [1]) is a geocentric orbit which combines altitude and inclination in such a way that an object on that orbit will appear to orbit in the same position, from the perspective of the Sun, during its orbit around the Earth. Put simply, an orbit happens because gravity is pulling the object towards the thing its orbiting, but the object is also moving sideways. This special position in high Earth orbit is known as a geosynchronous orbit. Carrington, 1859 17. SatCom #4: Satellite Orbit Altitude. 100% (1/1) A satellite in a sun-synchronous orbit still orbits the Earth, but does so in such a way that over the course of the day, its distance to the Sun will change in a consistent pattern no matter the time of year.
