About 1.3 million Earths could fit inside the Sun if you treat Earth as perfectly deformable and pack it with no gaps. If you keep Earths as solid spheres with realistic packing, the number is closer to about 950,000–960,000.

Quick Scoop

  • The Sun’s volume is about 1.3 million times that of Earth, which is where the popular “1.3 million Earths” figure comes from.
  • That 1.3 million assumes the Earths can be squished or cut up so there are no empty spaces between them.
  • When you account for the fact that Earths are spherical and cannot fill all space perfectly, more careful estimates give roughly 930,000–960,000 intact Earths fitting inside the Sun.

In everyday space facts, people usually quote 1.3 million Earths, but in a stricter, “no squishing allowed” sense, the realistic answer is just under a million.
