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 satellites orbit in the earth's equatorial plane at a height of 38,500 km. At this height, the satellite's orbital period matches the rotation of the Earth, so the satellite seems to stay stationary over the same point on the equator.Since the field of view of a satellite in geostationary orbit is fixed, it always views the same geographical area, day or night.eostationary orbits are circular orbits that are orientated in the plane of the Earth's equator. By placing the satellite at an altitude where it's orbital period exactly matches the rotation of the earth (35,800 km), the satellite appears to hover over one spot on the Earth's equator.
