The speed you need to go depends on the orbit you are trying to achieve. For low-Earth orbits (LEO) the satellite must be going about 18,000 miles per hour, but the higher the orbit, the slower you need to go.

It depends on the rocket's orbital height.

The formula is: Velocity = square root of ( G times M divided by R )

G is 6.67 x 10-11 N m2/kg2

M is the planet's mass (Earth's is 5.9736 x 1024 kg)

R is the distance between the rocket and the center of the planet (add the orbital height to the planet's radius at that point)

Make sure you use meters for the rocket's height.

For example, the international space station's orbital height is about 380 kilometers, and Earth's radius averages at about 6365 km, so we'll use 6,745,000 meters

square root of ( (6.67 x 10-11 N m2/kg2 ) x (5.9736 x 1024) / (6.745 x 106) = square root of (59,071,775) = 7686 meters per second = 7.7 km/s

Where does the rocket go when it is in space?

Like any other satellite, including the Moon, it stays up by centripetal force. Like a weight being whirled around your head on a string it would fly off in straight line if the force holding it in were to disappear. With the weight, this force is the tug of the string. With the space station it's gravity. The speed of the space station is just sufficient to keep it from falling to Earth, but also not so great that it would fly off into space. If the speed of the space station were to drop, it would fall to Earth.


How fast is the orbit moving around the earth?

The 'orbit' is the term we use to refer to the path that a body follows under the influence of its gravitational interaction with another body. The earth moves in its 'orbit' around the sun, always staying roughly 93 million miles distant from the sun. The earth makes one complete trip in its orbit around the sun in 1 year. In order to do that, the earth's speed in its orbit around the sun is almost 67,000 miles per hour ! At the same time, from the vantage point of an observer on the earth, the moon moves in its 'orbit' around the earth, always staying roughly 1/4 of a million miles from the earth. The moon makes one complete trip in its orbit around the earth in a little less than 1 month. In order to do that, the moon's speed in its orbit around the earth is about 2,300 miles per hour.


Do satellities orbit Earth in the exosphere?

No. If they did, air resistance would quickly slow them down and they would fall out of orbit. In order to be in a stable orbit, the satellites must be out of the atmosphere completely.


What are natural and artificial satellites?

Which will take more time to complete orbit around the sun mercury or earth?

Earth takes a lot longer to make one complete order around the sun than Mercury does. The time required for Mercury to make one orbit is equal to 88 Earth days (whereas one orbit for Earth is about 365 Earth days).
