All eight of them, plus (sometimes) the dwarf planet Pluto which has an orbit that brings it inside and outside the orbit of Neptune.
Probably, but impossible to tell as we are only just seeing planets within our own galaxy.

Most of the asteroids within our solar system can be found within the Asteroid Belt. Located between the orbits of Mars and Jupiter, the Asteroid Belt consists of millions of individual asteroids of varying sizes - from a speck of dust to hundreds of kilometers in diameter. The largest object within the belt is a dwarf planet - Ceres - which has a mass of 9.47x1020kg and a diameter of 476.2km.

Extrasolar planets are planets found orbiting stars other then our own.
There are 464 extrasolar planets, and 8 planets within our Solar System. This makes a total of 470 known planets.

The majority of the angular momentum of the solar system is found within the orbital motion of the planets around the Sun. This motion results in the spinning of the planets on their axes and the overall rotation of the solar system as a whole.

Extrasolar planets are planets found orbiting stars other then our own.
Moons can be found orbiting planets within our solar system and other planetary systems. They are natural satellites that range in size from small asteroid-like bodies to larger planets like Jupiter. Some moons, such as Earth's moon, are large enough to have their own gravitational pull.
Meteors can only be found within the atmospheres of planets. If they are on the outside the atmosphere they are called Meteroids. And if they have already penetrated the surface of a planet they are called Meteorites.
Most planets are found in the Milky Way galaxy, which is part of the Local Group of galaxies. Within the Milky Way, planets are most commonly found in the habitable zone around stars, where conditions may be suitable for liquid water and potentially life to exist.
