While our Sun is the largest object in our solar system, it's actually considered a medium-sized star. There are many stars much larger and more massive than our Sun.
Here are some examples:
* UY Scuti: One of the largest known stars, a red supergiant with a radius about 1,700 times that of the Sun.
* VY Canis Majoris: Another red supergiant with a radius roughly 1,800 times that of the Sun.
* Betelgeuse: A red supergiant in the Orion constellation, roughly 950 times the size of our Sun.
So, while the Sun is large to us, it's actually a fairly average-sized star in the grand scheme of the universe.
