Every solar system has at least one sun.


The terms sun and star are synonymous. We tend to use the term sun in the context of a planet. A planet has a sun which is itself a star.

A solar system is a star with at least one planet orbiting around it.

Many stars have one of more companion stars. Hence many solar systems will have two or more suns.
