Please note that "fastest" can be interpreted two ways: the actual speed a planet is traveling around the sun, or the actual time required for a given planet to complete it's orbit around the sun. In the first case, the larger a planet is, the greater it's mass and therefore the higher it's speed. One of the gas giants like Jupiter or Saturn being hundreds of times times larger than the inner planets like earth is traveling at immense speed. In the second case, the closer a planet is to the sun the shorter it's orbit will be and generally the faster it's trip will be. The planet closest to the sun and having the shortest obit around it is Mercury.
jupiter is the fastest spinning planet in our solar system.
Jupiter has the fastest rotation rate of any planet in our solar system, completing a full rotation on its axis in about 9.9 hours.
A moon? I don't think a planet orbiting another planet would be called a planet.
Venus is the biggest planet in our solar system that has no known satellites (moons).
The planet with the most moons in our solar system is Jupiter.
Mercury
jupiter is the fastest spinning planet in our solar system.
Mercury is the fastest orbiting planet in the inner Solar System, with an average orbital velocity of 47.87 km/s.
Jupiter is the fastest rotating planet int he solar system.
The planet Mercury has the fastest movement in our solar system.
Earth
Mercury moves the fastest 48 km/s
Yes, as now the Pluto is excluded from the solar system, it is the smallest and the fastest planet in the solar system.
Jupiter has the fastest rotation rate of any planet in our solar system, completing a full rotation on its axis in about 9.9 hours.
No. BY definition, an exo-planet is OUTSIDE our solar system, orbiting some other star.
The fastest moving planet in out solar system is Mercury, which is named after the roman god of speed.
Saturn is the second largest planet in the solar system and has an extensive orbiting ring system.
