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.
A satelliteâs orbit depends on its speed and distance from Earth. Below, the main orbit types are listed and defined. 1. LEO (Low Earth Orbit) - When a satellite circles close to Earth, itâs in Low Earth Orbit. Satellites in LEO are just 200-300 miles high. Because they orbit so close to the Earth, they must travel very fast (17,000 mph) so the gravity canât pull them back into the Earthâs atmosphere. a. Polar orbit-A satellite in polar orbit travels a north-south direction.
