They vary in speed, depending on what reference point you use. Some of the Perseid meteors this year were measured at about 160,000 miles per hour!
Most are moving more slowly, but the minimum speed is about 25,000 miles per hour, which is the speed that an object would have if it fell from space without any initial velocity.
Uranus moves at an average speed of about 6.8 kilometers per second (4.2 miles per second) in its orbit around the Sun. Compared to other planets in our solar system, Uranus moves at a moderate speed, slower than Mercury, Venus, Earth, and Mars but faster than Jupiter, Saturn, and Neptune.
The truthful answer is: That's just the way it worked out! However, you have to remember that Mercury was the messenger of the Gods, and because the planet travels very fast around the Sun - it was named Mercury, because who wants a slow messenger.
Very gradually
the particles in gases move very, very fast
aplanet is big but an astreroids move very fast in space
That would be Mercury. Venus also has no moons, but does not move as fast as Mercury.
Yes, they can move very fast.
No. While Mercury orbits the sun at a very high speed, its rotation is very slow.
They catch it with their claws and teeth, and move around with there very large tails, to swim very fast.
they move very slow
They crawl with their legs, and they swim really fast by turning around and flipping their tail back very fast repeatedly.
Because mercury is very fast dissolving metal
electrons (near light speed)
not very fast if you know what i mean
Compared to Earth, Mercury has a very fast year. It is 88 Earth days compared to Earth's 365.25 days.
mountain lions move very fast
Hummingbirds are really fast. They are very agile, as they can move with a very great ease
