Considerations regarding the question of where the solar system ends, starting from the bottom of the planets up to the theory that does not exclude the possibility that some comets are in orbit even beyond the current limit.
Clarifications on where the solar system ends
Generally Pluto is considered the last of the planets of the Solar System, its orbit is at an average distance of 5.900 million kilometers from the Sun, equal to one million times the width of the Atlantic Ocean between Europe and the United States .
However, some comets are thought to orbit halfway between the Sun and the nearest star, about two light-years away.
If so, the Solar System would span four light-years, which corresponds to approximately 40,000 million kilometers.
