Can planets be bigger than stars?

If you add mass to them, they get smaller, not bigger. So clearly you can’t get a planet bigger than the Sun. What about smaller stars? The smallest stars are dim red dwarfs, barely massive enough to maintain fusion in their core, and the smallest they can get is, well, pretty dang small.

Why are stars so big?

But for all other stars, their sizes are determined by that simple balance: the force from the outward radiation, at the surface, has to equal the inward pull of gravitation. Larger radiation forces means the star swells to larger sizes, with the largest stars of all swelling to billions of kilometers.
