SOLAR SYSTEM'S FASTEST PLANET
THE LONGEST LIST OF THE LONGEST
STUFF AT THE LONGEST DOMAIN NAME AT LONG LAST
What is the fastest planet in our solar system?
The fastest planet in our solar system was named after
the speedy messenger god Mercury.
Mercury travels at an average rate of 47.36 kilometers
per second 29.42 or miles per second in it's orbit around the Sun.
Mercury's top speed is 58.98 kilometers per second
36.64 or miles per second which translates to 131934.50 MPH.
As quick as Mercury travels, it spins quite slowly,
taking 58.6 Earth days for Mercury to spin once on its axis.
The fastest spinning planet is Jupiter, taking just
under 10 hours to spin once on its axis, rotating at a speed of 28,273 MPH.
Since Jupiter is a gaseous planet the poles rotate a
bit slower than the equator, Jupiter's day varies from 9 hours and 56 minutes
around the poles to 9 hours and 50 minutes close to the equator.
