There are 176 known moons that have been discovered so far in our solar system. These are small bodies that orbit a planet or dwarf planet.
169 moons orbiting six planets (includes Earth's Moon)
7 moons orbiting three dwarf planets
There are other bodies that orbit the Sun, or that orbit dwarf planet candidates. There are as many as 58 satellites of trans-Neptunian objects (TNOs) and around 104 asteroid moons (orbit around larger asteroids).
Venus does not have any moons. It is one of two planets in our solar system that does not have any moons, the other being Mercury.
Saturn has more moons than any other planet in our solar system.
There is only one Solar System; it is the star system with the star named Sol (our solar system). It is technically incorrect to refer to any other star system as 'a solar system.' Our star system is is also the only star system we know intimately enough (in fine enough detail) to know to have moons. It is not currently possible for us to detect moons orbiting extrasolar planets (planets orbiting other stars). There are 336 objects classified as moons in the Solar System.
No moons in our solar system have moons of their own, but it's theoretically possible.
Mercury and Venus are the only planets in our Solar System without any natural satellites (moons).Read more: Which_two_planets_have_no_moon
Jupiter has the most moons in our solar system, with over 80 confirmed moons.
Venus does not have any moons. It is one of two planets in our solar system that does not have any moons, the other being Mercury.
Saturn has more moons than any other planet in our solar system.
Yes. As far as I know, all of Jupiter's moons (and all other moons in the Solar System) have craters.

Jupiter has the most moons in our solar system, with at least 79 known moons. Some of its largest moons include Io, Europa, Ganymede, and Callisto.

Mercury is a planet in our solar system that does not have any moons.
Capella is a star, so it is not itself a solar system. Our sun is not a solar system, but it is part of the solar system along with the planets, moons, comets, asteroids and other objects. If Capella has any of those things, then it is part of a solar system.
