Most of the planets in our Solar System have multiple moons. Which two of the following planets have zero moons?

Mercury and Venus, the two closest planets to the Sun, have zero moons. Mercury doesn't have a moon because it is too close to the Sun and the Sun's gravity would steal away any object in Mercury's gravitational pull. The reason that Venus doesn't have a moon is not known, though several theories exist on the subject.
