Antares is significantly larger than the Sun. Here's a breakdown:

* Radius: Antares has a radius about 700 times larger than the Sun's radius.

* Volume: Since volume scales with the cube of the radius, Antares has a volume about 343,000,000 times larger than the Sun's.

To put this in perspective, if the Sun were the size of a basketball, Antares would be as big as a large house!
