How fast do satellites traval?
The speed of satellites varies depending on their distance from the Earth. The closer they are, the faster they must travel in order to remain in orbit.
Does the speed of planetary orbits increase the closer the planet is to the sun?
Yes. Planets (and other things) orbit at a higher speed the closer they are to the object they are orbiting.
How does a planets distance from the sun affect its orbit speed?
Since the gravitational effect of the Sun decreases with distance from it, the planets farther from the Sun do not have to move as rapidly to remain in orbit. (In fact, the speed is what establishes the orbit, not the other way around.) So the outer planets, in addition to having much farther to travel in their orbits, are also moving more slowly. This combination means that outer planets take very much longer to orbit the Sun than do the inner planets such as Earth. By comparison, the length of time it takes (in Earth years) for each of the outer planets to make one complete revolution around the Sun: Jupiter - 11.9 Earth years Saturn - 29.5 Earth years Uranus - 84 Earth years Neptune - 165 Earth years
What is an orbit in which a satellite travels at the same speed as the Earth's rotation?
Geosynchronous orbit.
What is the speed of a satellite that moves in an eliptical orbit around the earth?
If a satellite is in an elliptical orbit around the Earth, the Earth will be at one of the focii. The speed of the satellite will then constantly be changing. It will move the fastest when it is nearest to the Earth (perigee) and slowest when it is furthest away (apogee).
What will happen to the motion of a satellite if the satellite is put into an orbit where there is no sufficient velocity for rotation?
That would be "revolution", not "rotation". Let's assume you need a certain speed for a circular orbit. If the satellite (in this case) has a bit less speed, it will get closer and closer to the Earth, during half of its orbit. While doing this, its speed will increase; during the other half of its orbit, this speed will make it go away from the Earth again. The final result is that it moves around the Earth in an ellipse. This assumes, of course, that it doesn't approach the Earth too much. If it gets too close, it will be slowed down by the atmosphere, and eventually crash to Earth.

Where in our solar system are the planets which orbit fastest?
The closer planets are to the Sun the faster their orbit speed
If a comet is close to the sun how fast does it travel?
If any comet comes CLOSER to the Sun than Earth's distance from the Sun, its speed will be LARGER than that of Earth, which is 30 km/second.The exact speed will depend on how close the comet gets to Earth, and - to a lesser extent - on the exact shape of its orbit. If you know the orbital characteristics, you can get the speed using Kepler's laws. For a start, compare the orbit to Earth's orbit, using Kepler's Third Law.
Why orbit of earth is egg shape?
Well, a detailed analysis is probably quite complicated. But to give you a general idea, at a certain speed, the orbit would be circular - the attraction from the Sun is just enough to change the Earth's velocity (i.e., its direction) so that it becomes a circle - maintaining the speed. If the Earth moves slightly slower, then Earth doesn't have enough momentum to keep in a circle, so it would get closer and closer to the Sun, during half an orbit. However, that would also make Earth faster - in fact, fast enough to get away from the Sun again. The final result is a closed orbit, in the shape of an elipse.Well, a detailed analysis is probably quite complicated.

How long would be a second if the Earth would turn at a different speed?
a second will become less because it takes 365 days for the earth to orbit the sun and if the earth becomes faster it will take less day to orbit the sun, so if that happens time must go faster to keep up with the speed and time our earth takes to orbit the sun.
What is the maximum velocity that the Earth is able to revolve around the Sun without losing the ability to harbor life?
The speed of Earth is related to the position of its orbit around the Sun. At a higher speed, Earth would need to be closer to the Sun; at a lower speed, it would need to be farther from the Sun. In its current orbit, Earth moves around the Sun at a speed of about 30 km/second. Earth can't get much closer to the Sun (and therefore move faster) than that; for instance, Venus moves around the Sun at a mean speed of about 35 km/second, and it seems that Venus is too close to the Sun for life.
When two artificial satellite revolve around the earth the one's closer and the one's further. which one revolve the earth with higher speed?
The one that is closer will move at a higher speed. The same happens, for example, with planets revolving around the Sun - the planets closer to the Sun move faster.
Why does the earth move so fast?
We have no real idea of what caused the Earth to form in the orbit that it did (rather than one a little closer to the Sun or a little further away) but the speed of the Earth in its current orbit is fixed by its distance from the Sun. A closer orbit would be faster; a more distant orbit would be slower. Nor do we know why the Earth spins at its current rate. These things happened billions of years ago. We may NEVER know what happened way back when to cause things to be the way they are.
What happens to the shape of the orbit of a satellite orbiting the earth if the speed increases?
If the speed at every point of the new orbit is higher than the speed at every point of the old one, then the orbit is smaller, but it can have the same shape. ============================================ Another contributor added: going too fast may give the satellite an elliptical orbit, or may cause the satellite to escape the gravity of Earth if the velocity is too great
Does the speed of planetary orbits increase the closer the planet is to the sun?
Yes. Planets (and other things) orbit at a higher speed the closer they are to the object they are orbiting.
