NASCAR on Tuesday unveiled its 2015 schedules and the 36-race calendar for its premier Sprint Cup Series includes a three-race Western swing in March.
Geosynchronous - An orbit around Earth whose orbital period is equal to a sidereal day (23 hours, 56 minutes), irrespective of its inclination. - A person on a point on Earth, will see a satellite in this orbit in the same place in the sky at the same time of the day, everyday.
1 Sun-synchronous orbit: An orbit which combines altitude and inclination in such a way that the satellite passes over any given point of the planets' surface at the same local solar time. 2  Such an orbit can place a satellite in constant sunlight and is useful for imaging, spy, and weather satellites.he first satellite, Sputnik 1, was put into orbit around Earth and was therefore in geocentric orbit. By far this is the most common type of orbit with approximately 2,465 artificial satellites orbiting the Earth. Geocentric orbits may be further classified by their altitude, inclination and eccentricity.
