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.
Explain why the two outermost gas giant planets, Uranus and Neptune, appear so different from the innermost gas giant planets Saturn and Jupiter. Uranus and Neptune appear significantly different from Jupiter and Saturn because of the differing amounts of ammonia and methane in their outer atmospheres. The amount of ammonia decreases with distance from the Sun because it freezes out below 70 K. Thus Uranus and Neptune have little gaseous ammonia in their atmospheres. Methane is found in increasing abundance with distance from the Sun and gives a blue color to the planets.
