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.
Other geosynchronous orbits. Geosynchronous orbits, which are not geostationary, can be 'circular and inclined to equator' OR can be 'elliptical with any inclination'. E.g. QZSS orbit - Slightly elliptical, highly inclined (43 deg) orbit whose ground trace looks like this - NOT STATIONARY W.R.T GROUND.
