What is the most massive star known?
The largest known star is UY Scuti, a hypergiant with a radius somewhere around 1,700 times larger than the sun. Its mass, however, is only 30 times that of our nearest star. If R136a1 swapped places with the sun, it would outshine our closest star as much as the sun currently outshines the moon.
Is Jupiter a failed star?
