Okay, so all the planets and their moons rotate, and thus generate a gravitational field (at least I think that is what creates it). So does this mean that the Sun is rotating as well? Okay so it is apparently firey gas and liquids on the outside at impossibly hot temperatures, but does it mean that there may be a rotating core inside??
