VV Cephei A is absolutely massive compared to our Sun. Here's a breakdown:

* VV Cephei A: A red hypergiant star with a radius estimated at 1,600 times the radius of our Sun.

* Our Sun: A yellow dwarf star with a radius of approximately 695,000 kilometers.

Putting it into perspective:

* If you were to shrink the Sun down to the size of a basketball, VV Cephei A would be as big as a medium-sized car.

Important note: The exact size of VV Cephei A is still being debated, with some estimates putting its radius even larger.

So, the answer: VV Cephei A is vastly larger than our Sun, making it one of the largest known stars in our galaxy.
