How does the size of the Milky Way galaxy compare to the solar system?

The Milky Way galaxy is much larger than the solar system. The Milky Way is a collection of billions of stars, including our sun, while the solar system consists of just one star (the sun) and its planets, moons, and other celestial bodies. The Milky Way is about 100,000 light-years in diameter, while the solar system is only a few light-hours across.
