The reason is tied to the origins of the Solar System as a primordial Sun surrounded by initially randomly swirling clouds of dust and gas. Pulled towards the Sun by gravity, these clouds became denser, with internal collisions leading to a preferred direction of motion. Like water spiralling round a plughole, the collapsing clouds swirled in this direction at an ever-faster rate, eventually becoming dense enough to collapse under their own gravity and form spinning planets and moons. The one exception is Saturn's moon Hyperion, which seems to have undergone a very violent impact, turning it into a potato-shaped rock that tumbles chaotically through space. RM
They both spin on an axis.
Yes, all the outer planets have at least a dozen moons.
No. Mercury and Venus have no moons.
All of the Jovian planets in the solar system have rings and more than eight moons. Neptune has the fewest known moons of the giant planets; : 14.
All matter has a gravitational pull. Even you have a gravitational pull too. It is just that since your mass isn't quite as big as the Earth, your you can't see things moving towards you. When you jump, the Earth pulls you down. THat is cause the Earth is considerably bigger than you and you are attracted to the Earth. Some planets have more moons because of their mass. Since they are bigger and more massive, they pull much more stuff around them to orbit.
They both spin on an axis.
All of them have moons.
Yes, all the outer planets have at least a dozen moons.
No, Mercury and Venus do not have moons.
All the planets that we know about spin, yes. Some spin faster or slower, or on a different axis, but they all spin.
Yes. Planets and moons come in all sizes and colors.
In our Solar System all planets have moons, except for Mercury and Venus.
Yes. All four of the outer planets have multiple moons.
No. Mercury and Venus have no moons.
No. Mercury and Venus do not have moons.
The gas planets have more moons. Of all the gas planets non has fewer than 14 moons. Of the rocky planets, none has more than two. Mercury and Venus have none at all.
