While it might feel big to us, the Sun is actually a medium-sized star. There are many stars much smaller than our Sun, called red dwarfs.

Here's why:

* Size comparison: Red dwarfs are significantly smaller and cooler than the Sun. They can be as small as 10% of the Sun's diameter.

* Prevalence: Red dwarfs are the most common type of star in the Milky Way galaxy.

So, while the Sun might seem gigantic from Earth, there are many, many stars much smaller out there!
