The planet that spins on its axis at the fastest rate is which one of the following solar system planets?

Options :
  1. Mercury
  2. Earth
  3. Jupiter
  4. Saturn
Answer and Explanation :-

Answer: Option 3


The fastest spinning planet in the solar system 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. The fast spin of Jupiter round its axis creates an equatorial bulge easily seen through an Earth-based amateur telescope.
