The planet is about 2.4 times the radius of Earth.

That would make for one long-a*s day!

Come to think of it, that means all the Muslims would starve to death during Ramadan.

Hmmm. The diameter of Jupiter is more than 22 times earth's and a Jovian day is about 10 hours long. The moon otoh has a diameter 3.66 time smaller than earth's and a solar day of about 29.53 days. The earth was "despun" by the moon over the past several billion years, in fact, even today, the length of day increases by about 0.0015-0.0020 seconds per century.

Maybe you can explain to me the connection between planetary radius and period of rotation, because I just don't get it.
