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.
There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface. satellite that orbits directly above the equator has zero inclination. If a satellite orbits from the north pole (geographic, not magnetic) to the south pole, its inclination is 90 degrees. Orbital inclination is the angle between the plane of an orbit and the equator.
