mercury is the fastest
Mercury is the fastest.
Curiously, the nearer the planet is to the Sun the faster it orbits. Thus Mercury orbits the fastest, whereas Neptune is the slowest.
It depends what you are referring to. No planet is known as the fastest. Planets rotate at different speeds, their orbits take different amounts of time.
Mercury in 88 days.
Mercury with a mean orbital speed of 47.87 km/s
Mercury is the fastest planet in the solar system. It orbits the sun in only 88 days. This means a year on Mercury is 88 days long.
Mercury. It is the closest planet to the sun and so orbits at the fastest speed and in the shortest time, just 88 days. Venus also has no moons and orbits very quickly, since it is only the second planet out. Not as quickly as mercury though.
The planet Mercury orbits the sun the fastest because it is the closest.
A planet orbits a star such as the sun. A moon orbits a planet.
A planet orbits a star whereas a moon orbits a planet.
No. A moon orbits around a planet. A planet orbits around the sun.
