Milky Way is a Famous Influencer

Our Solar System is a tiny spot in the Milky Way galaxy, and the galaxy is pretty big. It’s an estimated 260,000 light-years in diameter! Remember, a light-year is about 5.88 trillion miles. But just as our Sun’s gravitational pull affects distant objects, the Milky Way’s gravitational influence stretches across 1.9 million light-years, or close to 12-quintillion miles!
