What happens when satellite speeds up?

If the satellite is moving too quickly then the gravitational attraction between the Earth and the satellite is too weak to keep it in orbit. If this is the case, the satellite will move off into space. This occurs at speeds around or above 11,200 metres per second (m/s).

How many hours does it take this satellite to make one orbit?

A satellite at this height takes 12 hours to complete an orbit. As the satellite moves, the Earth rotates underneath it. In 24-hours, the satellite crosses over the same two spots on the equator every day. This orbit is consistent and highly predictable.

What happens when a satellite speeds up?

How long does it take a satellite to complete an orbit?

In this highly inclined orbit, the satellite moves around the Earth from pole to pole, taking about 99 minutes to complete an orbit. During one half of the orbit, the satellite views the daytime side of the Earth. At the pole, satellite crosses over to the nighttime side of Earth.

What determines how fast a satellite moves around the Earth?

(NASA illustration by Robert Simmon) The height of the orbit, or distance between the satellite and Earth’s surface, determines how quickly the satellite moves around the Earth. An Earth-orbiting satellite’s motion is mostly controlled by Earth’s gravity.

Where do geostationary satellites orbit the Earth?

Geostationary Satellites 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.

What is the radius of the Earth in circular orbit?

•Calculate the velocity of an artificial satellite orbiting the Earth in a circular orbit at an altitude of 200 km above the Earth’s surface. •ANSWER Radius of Earth = 6,378.14 km GM of Earth = 3.986005×1014m3/s2
