The close-in ones move fast, the far-out ones move slower. It's governed by Kepler's third law.
Fast and slow are comparative words. Some planets orbit faster than others. The planets nearer the sun orbit faster than those farther away.
It's in an elliptical orbit around the Sun, like all the planets. So its distance from the Sun varies. When it's nearest to the Sun it moves fastest. (This can be explained from the Law of Gravitation.)
No planet is made of glass, as far as I know. The giant planets - Jupiter, Saturn, Uranus, Neptune - are large, and made mostly of gas. However, they are not fast-moving.The inner planets - Mercury, Venus, Earth, Mars - are slow, fast-moving, and made basically of rock.
U-235 can fission by absorbing fast or slow neutrons, but it has a much larger cross section for slow ones, that is it absorbs slow neutrons much more readily than fast ones. This enables moderated reactors to operate with low enriched (5% or less) or even natural uranium, whilst fast reactors must have much more highly enriched uranium, ie with more U-235. The ultimate is the nuclear bomb, where almost pure U-235 will fission entirely with fast neutrons, if enough of it is suddenly put together.
advantages of slow and fast changes
yes because with out its orbit it would be as slow as a snail
ones fast and ones slow
It depends on their size, mass, distance and strength of gravity.
Yes, all the planets are constantly in orbit and use up no energy because in space there is nothing to slow them down.
fast ones slow ones big ones small ones

all the planets stay in orbit around the sun because of the sun's gravitational pull. The high orbital speed that keeps the planets from falling all the way into the sun and since there is no friction in the vacuum of space , that speed dosen't slow down.
they are all equally super fast... no slow ones.
A planet in an elliptical (oval) orbit will move faster as it gets to its closest point to its sun, and slow down as it reaches its furthest point. A planet with a truly circular orbit will have a constant speed.
Well Venus keeps stopping and starting and crashing because its where women come from right? so its pretty fast when it should be slow and really slow when it should be fast. good question by the way.
Jupiter orbits the sun much more slowly than the Earth does.
All the planets stay in orbit around the sun because of the sun's gravitational pull. Now you are probably wondering why the planets don't all get sucked into the sun,well it is the high orbital speed that keeps the planets from falling all the way into the Sun and since there is no friction in the vacuum of space, that speed doesn't slow down.
