The diameter of our solar system depends on how we define its boundary. Using the orbit of Neptune as a reference, the diameter of our solar system is about 7.4 billion miles or 80 astronomical units (AU)1. However, if we include the Oort Cloud, a region of icy bodies that extends far beyond the planets, the diameter of our solar system could be as large as 12 trillion miles or 2 light years2.
