Space factSun
The Sun is so massive that it could hold about 1.3 million Earths inside its volume. Even if you just wanted to cover its surface with Earth-sized spheres, you’d still need roughly 40,000 of them. Despite its enormous size, the Sun is actually considered a medium-sized star—many stars out there make it look tiny.
