* Stars are vastly different sizes: Stars come in a huge range of sizes, from tiny red dwarfs to gigantic supergiants. Earth is relatively small compared to even the smallest stars.
* We don't know all the stars: We can only observe a limited portion of the universe. There are likely countless stars out there we haven't even detected yet.
However, we can say this:
* Almost all stars are bigger than Earth: The vast majority of stars are significantly larger than our planet.
* Red dwarfs are the exception: Red dwarfs are the most common type of star, and they are much smaller than Earth.
Think of it this way: Imagine a beach with sand grains representing stars. Earth would be like a tiny pebble. There would be millions of sand grains bigger than that pebble, even though we can't count every single one.
