Because Mercury is so much more closer to the Sun than Pluto is. It appears that Mercury is moving faster because it's orbit around the sun is a lot smaller, they could both be moving at the same speed and it would still take Pluto a lot longer to complete it's orbit.
Compare to 2 runners running laps on two different tracks.
One track is one mile around, the other four miles around.
They both start at the same time and at the same speed, say four miles an hour.
While the runner on the four mile track has done one lap, the runner on the one mile track has done four laps, as is the same for Mercury and Pluto.
Because of the size of tracks and orbits it appears that one is moving faster than the other, but they have both covered the same distance at the same speed. Because of it's shorter "lap", Mercury will complete 1008.59 laps before Pluto completes it's first.
If you mean faster than the Earth, then the planets Mercury and Venus orbit faster. This is because they are closer to the sun.
Mercury is the smallest of the eight planets.
Mercury is a rocky planet. The inner planets (first four planets from the sun) are rocky planets (which means that you could stand on them) and are the smallest. While the outer planets (last four planets from the sun) are gas planets and the biggest.
Orbiting faster than any planet in our Solar System, Mercury goes around the Sun about every 88 Earth days. it is also the smallest planet, and the closest to the Sun. Mercury has no known satellites. Venus orbits the Sun about every 224.7 Earth days. It is the second-closest planet to the Sun, and also has no known satellites.
Terestrial planets Mercury, Venus, Earth and mars.
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 is Mercury.
Mercury.
Mercury.
the fastest planet that orbit's the sun is mercury.
Mercury is the Speediest planet in our solar system.
Mercury is a planet itself, and it does not have any planets to it.
Mercury doesn't "have planets".
The planet Mercury moved faster than the other planets so the Romans named it after the god, Mercury, who was famous for his swiftness in delivering messages.
This is false. Mercury is the "fastest" planet, with Venus and Earth next. IN fact, the orbital speed of any planet is inversely related to the distance from the Sun; close-in planets orbit faster than farther-out planets.
Neptune is a gas planet, but mercury is not. Mercury is a rocky inner planet, one of the four terrestrial planets.
Yes! The closer planets are to the sun the faster they go. Since Murcury is closest, it is the fastest.
