Betelgeuse is a red supergiant star, and its radius is not a fixed value. It pulsates, meaning it expands and contracts over time.

However, we can provide an estimated range based on recent observations:

* Estimated Solar Radii: 760 to 950 times the radius of the Sun

This means Betelgeuse is huge. If it were in our Solar System, it would extend out past the orbit of Jupiter!

It's important to note that these are just estimates, and the actual radius of Betelgeuse could be slightly different.
