* Radius: Betelgeuse's radius is about 700-1000 times larger than the Sun's radius.

* Volume: If you consider volume (the amount of space an object takes up), Betelgeuse is millions of times larger than the Sun.

Think of it this way: if the Sun were the size of a basketball, Betelgeuse would be as large as the entire Earth!

This massive size is what makes Betelgeuse a red supergiant. It's nearing the end of its life and is likely to explode as a supernova in the coming thousands of years.
