They are examples of moons. Pressumably, many planets around other stars will also have moons, although as far as I know, this hasn't been confirmed yet.
About 120 planets are in our solar system.
It is an orrery.
Yes. Earth has just one moon but other planets in our solar system have many more than this!
There are more than 52 moons in the solar system - Jupiter alone has 67 confirmed moons to date.
Out of the planets in our Solar System, Jupiter has the most moons. It has 63 confirmed moons.
I believe you mean "planets" because in no way do plants, which grow in various climates out of the earth's crust with the right amount of sunlight and water to survive through photosynthesis, have "moons". To answer your question, no, not all planets in the solar system have moons, but six out of eight do. - Earth has 1 moon. - Mars has 2 moons. - Jupiter has 64 moons. - Saturn has 62 moons. - Uranus has 27 moons. - Neptune has 13 moons. Mercury and Venus have 0 moons.
Moons are larger, obviously.
There are a total of 214 moons orbiting planets in our solar system.
Saturn has more moons than any other planet in our solar system
You can see the whole solar system and its moons on NASA's Solar System Exploration website (solarsystem.nasa.gov). It provides detailed information on each planet, its moons, and various missions exploring our solar system.
The planet with the most moons in our solar system is Jupiter.
The Solar System are including about 60 Moons
