Here's why:

* Our Sun: Our own Sun is a star, and it's about 109 times wider than Earth.

* Red Dwarfs: The most common type of star in the universe are red dwarfs, which are much smaller than our Sun, but still significantly larger than Earth.

* Massive Stars: There are also stars much larger than our Sun, some with diameters hundreds of times bigger than Earth.

So, while there are some extremely small, faint stars called brown dwarfs that might be smaller than Earth, they are rare. The vast majority of stars are significantly larger than our planet.
