In addition to the planets and moons seen in this simulated photo, our solar system contains a star, asteroids and comets, and dwarf planets such as Pluto.

The outer comet ring orbits from 35 to 90 astronomical units from the star; our solar system's analogous Kuiper Belt extends from about 30 to 50 astronomical units from the sun.

Although our solar system only has one star, most stars like our sun are not solitary, but are binaries where two stars orbit each other a pair, or multiples involving even more stars.
