From this site, it states that:

The Sun spins faster at its equator than at its poles.

I have also read somewhere that the gas giants (gaseous planets like Jupiter, Saturn, Uranus, and Neptune) also rotate faster at the equator than at the poles. Why this is so?

Editor: this is specifically about difference in angular rates, not linear speed.

  • $\begingroup$ Are you asking why the equator is faster in terms of raw speed (e.g. Km/h) or in terms of how long it takes to complete one full rotation? $\endgroup$

  • $\begingroup$ Sorry, but what is meant by raw speed? I do not know that. $\endgroup$

    $\begingroup$ As I said km/h. The earth has a different speed at the equator compared to the poles in km/h but not in rad/h. The sun has a difference in both so I am asking which you are talking about $\endgroup$

  • $\begingroup$ If you just look at the atmosphere, the Earth too spins at a different rate at different latitudes. For stars and gas giants, we're looking at the atmosphere. $\endgroup$

    $\begingroup$ Does this answer your question? Why does the outer layer of the sun have differential rotation? $\endgroup$ Aug 6 at 3:55
