What visual evidence do scientists have to support the fact that jupiter is the fastest-rotating planet in the solar system?

Jupiter is the 5th and most fastest spinning planet it completes an orbit around 11.86 years every year.

Explanation:

Jupiter is the biggest planet in our solar system, it's a gaianet and gaseous planet about 2.5 tims of all the planets combined. Like other planets jupiter doesn't have any defined solid surface, as a result of its rotation it has an oblate spheroid bulge along the equator and at it's boundaries are greater turbulence of storms and popular amongst them is the great Red storm.A complete day at the equator can be estimated by just nine hours and 50 minutes at the poles.
