A satellite in a geostationary orbit orbits the Earth at around 22,300 miles above the equator. Geostationary satellites appear to be stationary in the sky relative to a fixed point on the Earth's surface, making them ideal for communication and weather monitoring.
The circumference of the Earth one foot above the equator would be approximately the same as the circumference at the equator itself, which is about 24,901 miles.
No sir it is not. The equator is the imaginary line that goes horizontally (left to right) around the Earth. London is a city in Europe, all of Europe is above the equator.
No, a satellite in a polar orbit does not remain at the same point over the equator. Instead, it travels over the Earth's poles, allowing it to pass over different points on the equator as the Earth rotates beneath it. This means that the satellite covers a different section of the Earth's surface with each orbit, providing global coverage over time.
The distance around the Earth's equator is approximately 4,007,500,000cm.
37,000 km above the earth's equator
an orbit that is about 36000km above the Earth's surface and in which a satellite is above a fixed spot on the equator.

Yes, that's correct. A geostationary satellite orbits the Earth at the same rate that the Earth rotates, so it appears to be stationary relative to an observer on the ground at the equator. This means it always stays above the same point on the Earth's surface.
A Geostationary orbit - it means that the satellite will always stay above the same point on Earth. Hope that helps
Any orbit of the Earth must have its center at the Earth's center. So there are two choices for any Earth satellite: -- Orbit above the equator, never crossing any land that isn't on the equator, and never visible to people who aren't located close to the equator, or else -- revolve in an orbit that's inclined to the equator, sooner or later crossing every point on Earth that lies within the N/S latitudes equal to its inclination, and eventually visible to the majority of Earth's population. A satellite can't, for example, orbit entirely above the Tropic of Cancer, or the Arctic Circle. It must either cross the equator twice in each orbit, or else stay permanently above the equator.
Satellites typically orbit in low Earth orbit (LEO) at altitudes ranging from 160 to 2,000 kilometers, in medium Earth orbit (MEO) around 10,000 kilometers, or in geostationary orbit (GEO) at around 35,786 kilometers above Earth's equator. The altitude depends on the purpose and function of the satellite.
There is no set inclination of a satellites orbit to the earth's equator. Once in space, the spin of the earth or where it's poles happen to be become irrelevant to the satellite. Many satellites like spy and weather satellites orbit over the two poles (north and south) while communication satellites are placed in orbit directly above the equator at a height that is synchronised with the earth's orbit. This way they stay permanently above the same place on the equator and do not APPEAR to move at all.

A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude. The further away it is then the longer it will take. You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)
Geostationary satellites orbit high above the surface of the earth at about 35,000km, directly above the equator. The take the same time to complete one orbit as the earths surface as it rotates meaning it is always above the same point on earth. They are used for TV and telephone signals as well as weather imagery, among other things. A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude.

The National Oceanic and Atmospheric Administration, or NOAA, has Geostationary Operational Satellites 22,300 miles above the Earth's equator. Since the satellite is rotating as fast as the Earth, it can constantly monitor weather systems and capture pictures.
