Why are Venus and Mercury the only planets in the Solar System without a moon?
I'm not sure of the answer, but I believe the tidal forces of the sun are the likely cause.
As one Answerer noted, Earth's Moon was the possible result of a collision. Mar's two moons are likely captured asteroids. So we may be lucky to have our Moon considering how close we are to the sun and the relative puniness of our gravitational field.
Just a guess but I suspect any loose small stuff in the early solar system was picked up by the sun due to its greater gravitational influence. Our moon may very well be a fluke thanks to the collision with a mars sized planet durring the accretion. At our distance the gravitational attraction between earth and the moon is probably large enough ( at at that time it was far larger since the moon was MUCH closer ) to offset the attraction of the sun.
