And that's what formed our moon. Why some planets have many moons is basically because of their size. The planets in our solar system that have more moons are the large planets, Jupiter, Saturn, Uranus and Neptune. They're so big that they can collect a lot of moon. If comets swing by them, they can sometimes absorb comets, they can grab asteroids.
Best Answer: The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days.The Moon spends the extra 2.2 days catching up because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth. Re-worded it a little.ne solar day = 24 hours, and 29.53 solar days is the synodic month. You are correct in saying it takes 27.3 solar days for the moon to orbit the earth-that's the sidereal month. But in addition to the moon orbiting the earth, the earth-moon system is orbiting the sun. That's why the sidereal and synodic months differ.
