Because it is nearer to the Sun than all of the other planets. Its orbit is inside that of all of the other planets, so it shorter.
No, Jupiter has the fastest rotation and Mercury has the fastest orbit.
the fastest planet that orbit's the sun is mercury.
Mercury is the planet that revolves fastest around the sun, completing an orbit in about 88 Earth days.
If you mean faster than the Earth, then the planets Mercury and Venus orbit faster. This is because they are closer to the sun.
The fastest planet around the Sun is Mercury, which takes 88 days to orbit. The planet with the fastest rotation is Jupiter, which takes 10 hours to rotate.
The earth is moving fastest in its orbit at the moment of perihelion, when it is closest to the sun. the happens around January 3.
Curiously, the nearer the planet is to the Sun the faster it orbits. Thus Mercury orbits the fastest, whereas Neptune is the slowest.
The planet that is closest to the sun will orbit the fastest because its orbit is much smaller than the others. Mercury would be the correct answer. mercury because the first one has less distance to travel
Mercury is the Speediest planet in our solar system.
Being the planet closest to the Sun, Mercury is the planet that travels fastest in its orbit, and the planet that completes an orbital revolution in the shortest time. Mercury circles the sun in only 88 earth days.
Mercury...cos it's closest therefore has the shortest orbit
Mercury is the fastest planet because it has the shortest orbital period around the sun. It is closest to the sun, which results in a stronger gravitational pull that causes it to travel faster along its orbit compared to other planets.
