Here's why:
* Size: The Sun is considered a yellow dwarf star, which is a fairly common type of star. It's larger than many other stars, but there are many much larger stars out there, including red giants and supergiants.
* Brightness: The Sun is about average in brightness as well. There are many stars that are much brighter and much dimmer.
* Mass: The Sun's mass is also average for a star. Some stars are much more massive, while others are much less massive.
So, while the Sun might seem huge to us, it's actually a fairly average star in the grand scheme of things.
