A polar orbit (as opposed to an equatorial orbit) passes over the poles, north and south. A low orbit is relatively close to the Earth (or other object being orbited), it might be a few hundred miles up.
No. A geosynchronous orbit is one in which the satellite stays approximately stationary with respect to a point on the earth's surface. This is not possible in any orbits which are not in the...
Sub polar low pressure zone happens due to circular shape of earth. The dense , tightly packed air of polar high pressure zone drags southward in Northern Hemisphere at the surface. As they move,...
Low earth orbit is generally defined as orbiting the Earth at between 200 and 2,000 kilometers (124 to 1240 miles) above the Earth's surface.
Below 200km, the gravity of the Earth causes the orbit...
Low Earth orbits decay into lower Earth orbits and then re-entry into the atmosphere happens and the orbiting thing either burns up in the air or crashes into the Earth somewhere.
