Q:

Dear 100 Hour Board,

If the Earth had two moons, would they go through their moon phases simulatenous together or would they be at different phases throughout the month?

- the Tide

A: Dear The Tide (Probably not to be confused with The Crimson Tide -- the mascot of the University of Alabama who were my biggest disappointment of the 2005 football season. It can't be that hard to find some sort of an offence, but then again BYU seems to have problems with their defense.),

The answer to this is it depends. Basically it depends on where the moons are at in location to each other and how far apart the moons are. It is possible for the two moons to be in phase with each other, but it is more likely that they would be out of phase. If you look at the two moons of Mars you get a good example of this as the two are generally out of phase with each other. I sure hope this helps. Please don't hate me.
