Vega is significantly larger than our Sun. Here's a breakdown:

* Radius: Vega's radius is about 2.36 times the Sun's radius. This means it's over twice as wide as our star.

* Volume: Because volume scales with the cube of radius, Vega's volume is roughly 13 times the Sun's volume.

* Mass: Vega is slightly more massive than the Sun, with a mass about 2.1 times that of our star.

While Vega is larger and more massive than the Sun, it's important to remember that it's still a relatively small star compared to some of the giants and supergiants in the universe.
