You may be familiar with hibiscus, known as âsour teaâ in Iran, a delicious and refreshing summertime drink. Originally from Angola, hibiscus is now cultivated throughout tropical and subtropical regions, especially in Sudan, Egypt, Thailand, Mexico, and China.
High Earth Orbit. When a satellite reaches exactly 42,164 kilometers from the center of the Earth (about 36,000 kilometers from Earthâs surface), it enters a sort of âsweet spotâ in which its orbit matches Earthâs rotation.his special, high Earth orbit is called geosynchronous. A satellite in a circular geosynchronous orbit directly over the equator (eccentricity and inclination at zero) will have a geostationary orbit that does not move at all relative to the ground.
Likewise, the moon orbits Earth. Many artificial satellites also orbit Earth. When it comes to satellites, space engineers have different types of orbits to choose from. Satellites can orbit Earth's equator or go over Earth's North and South Poles . . . or anything in between. They orbit at a low altitude of just a few hundred miles above Earth's surface or thousands of miles out in space. The choice of orbit all depends on the satellite's job.
