Nota: be careful not to confuse the synchronous orbit of a satellite with a satellite synchronous rotation. As the name suggests, it has something to do with syncing up with the sun. For low orbits, the inclination turns out to be slightly over 90°. Sun-synchronous orbits are popular around Earth, and the Mars Reconnaisance Orbiter uses one as well (so I think Wikipedias definition as a geocentric orbit is wrong).Considering that probably any rotating body has some oblateness, is a sun-synchronous orbit always possible, or are there some fundamental limitations that make sun-synchronous orbits impossible around certain … A sun-synchronous orbit is an orbit around the Earth, where the movement of the satellite always looks the same when viewed from the Sun. Create your account. A common kind of geosynchronous orbit is called a geostationary orbit, where the object orbits above the same part of the Earth at all times. Often, satellites in SSO are synchronised so that they are in constant dawn or dusk – this is because by constantly riding a sunset or sunrise, they will never have the Sun at an angle where the Earth shadows them. How much gravitational potential energy must a 3140-kg satellite acquire in order to attain a geosynchronous orbit?
