UY Scuti is a star that is within our galaxy, the Milky Way. It can be located in the constellation of scutum. UY Scuti is one of the largest Giant Stars in The Milky Way if not possibly the universe. It is not as some might think in our Solar System, it is the centre of its own Solar System. However as we are unable to measure all the stars, we will not know if that is the case that it is the largest in Universe.
