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.
Geostationary and low orbit satellites. Geostationary satellites orbit the Earth above the equator [equator: An imaginary line that goes around the centre of the Earth, remaining equal distances from the north and south poles. It has a latitude of 0Â°.] once every 24 hours, while low polar orbit satellites pass over the poles and have much shorter orbit times.
