   Where does the Solar System end?

   • If you measure by edge of the Sun's magnetic fields, the end is the heliosphere. If you judge by the stopping point of Sun's gravitational influence, the solar system would end at the Oort Cloud. Narrator: Where is the edge of the solar system? The answer is not so simple. You could say it's where the planets end.

   How far away is the Sun from a star system?

   • The Sun is roughly 4 light-years away from the closest star system, the Alpha Centauri system. The planets in our Solar System, however, aren't even close to that far away from the Sun. Where does our Solar System end? Is the edge considered to be the orbit of Neptune, the Kuiper Belt, the Oort Cloud, or something else?

   How big is the Sun compared to Earth?

   • The Sun is about 100 times wider than Earth and about 10 times wider than Jupiter, the biggest planet. The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around it – the planets, asteroids, comets, and tiny bits of space debris.

   Is the Kuiper belt the edge of the Solar System?

   • "If one narrowly defines the solar system as just the sun and its planetary bodies, then the edge of the Kuiper Belt can be considered to be the edge of the solar system," Reisenfeld said. But this definition of the solar system is considered to be far too simple by some astronomers, such as Caltech's Mike Brown.
