The larger the orbit, the longer the period of revolution. The Space Shuttle, when it is in orbit, revolves once around the earth in about 90 minutes. The moon ... and any other satellite at a distance of about a quarter million miles from earth ... takes about 27 days to revolve once around the earth.

A geosynchronous satellite appears to remain over one spot on the earth its orbital radius is 4.23 x 107 calculate its speed in orbit?
If the satellite appears to remain motionless over one spot on the earth, then I don'tneed to know the radius or anything else about orbital mechanics to calculate its period.It had better be equal to the earth's rotation period of 23hours 56minutes and about 4 seconds.
What is the radius of asteroid vesta?
The average orbital speed of the asteroid Vesta is 19.34 km/s.
What is the orbital speed of Titan?
average orbital speed of 9.69km/s
Which term refers to the speed at which a planet travel in its orbit?
Orbital velocity refers to the speed at which a planet travels in its orbit.
Why at height the artificial sateillte not pulled toward the earth?
The satellite is being pulled by the earths gravity all of the time, but the satellite also has an orbital velocity, meaning that is is travelling at high speed. These two opposing forces balance out, the 'sideways' speed of the satellite wants to take it away into space, but the gravity of the earth is always pulling it in. The satellite maintains its speed as there there are no frictional forces to slow it down in space, so it maintains an orbit.
How is orbital speed determined?
Orbital speed of a satellite: v - orbital speed G - gravitational consatnt R - radius of earth h - height of orbit
At what height from the surface of the earth the total energy of the satellite is equal to its potential energy at a height of 2R from the surface of earth?
This question cannot be answered because:the total energy of the satellite includes its kinetic energy and that depends on its orbital speed. This is not specified;it is not clear what you mean by "potational": is it a typo for rotational or potential?what is R? The radius of the earth or the height of the satellite or some other measure?
How does a satellite get into the exosphere?
It has to be carried there by a rocket, which takes it to the required altitude and orbital speed.
Why scientist must carefully set the right orbital speed of a satellite orbiting earth?
Scientists must carefully set the right orbital speed for a satellite that will be orbiting Earth, so that it will orbit correctly. The wrong speed will have the satellite move too fast, or too slow, skewing information and possibly causing the satellite to fall out of orbit and back to the planet's surface.
When does a satellite have the greatest acceleration?
When it is closest to the planet.One of the components of the acceleration, the normal acceleration, is equal to v2/r, where v is the satellite's speed and r is the radius of the current orbit followed by the satellite. So, the smaller the radius, the higher the acceleration.
An earth satellite in a elliptical moves with what speed?
The speed is variable; faster while closer to the Earth, and slower further away. But the actual speed varies by the orbital distance.

How does a change in radius effect linear velocity?
For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.
What is the name for a planet's speed in its orbit?
It is the orbital velocity (speed and direction) or orbital speed (rate of motion). It is usually stated as "average orbital speed" but is actually "mean orbital speed."
How fast do a GPS satellites travel?
This actually depends on the orbital radius, or distance from Earth's surface (or center). The further away the satellite is, the slower it travels to stay in orbit (related to Kepler's second law). A satellite that is really close to the atmosphere and barely in space needs to travel at about 7800m/s. A satellite can speed up and increase its tangential velocity to make its orbit bigger. A bigger orbit results in a lower speed. Interestingly, this means that an orbiter speeds up to slow down. Likewise, a satellite in a high orbit can fire its engines backwards to reduce its speed to get into a smaller, faster orbit, ultimately speeding up. ================================ In an orbit that's not a perfect circle, the speed in orbit is always changing. The satellite moves faster when it's closer to the Earth, and slower when it's farther out.
Why must a horizontally moving projectile have a large speed to become an earth's satellite?
At lower speed, the object will fall back on the ground. Since, earth is curved, if the object has enought speed, the object can try to fall beyond the curvature of the earth. Thus, it will not hit ground at all. The speed to achieve it is around 8 km/s. If the object is faster than 11.4 km/s then the object will never return. It is called escape velocity.
