Scientists believed that, the term solar system doesn't only include, the Sun and the 8 planets which are the: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, or the asteroid belt and all the Dwarf planets: Haumea, MakeMake, Eris, Ceres and Pluto, but also the trans-neptunian region known as the Kuiper Belt, that is believed to be the home of most comets in the universe.
But many astronomers suggest that Kuiper Belt is not yet the very extent of our Solar System, but the theoretical region called as "Oort Cloud", a bûbblè-like shell composed of uncôu-ntable- interstellar bodies, that surrounds the solar system.
The end of the solar system is about 122 astronomical units (AU) away from the sun, where one AU is 93 million miles (150 million kilometers). That's about three times as far out as Pluto, which is about 40 AU from the sun, or about six times farther away from Earth than Neptune's orbit.
