UY Scuti is a red supergiant star located in the constellation Scutum. It is one of the largest known stars, with a radius approximately 1,700 times that of the Sun. UY Scuti is classified as a variable star, meaning its brightness changes over time due to pulsations in its outer layers. This massive star is situated about 9,500 light-years away from Earth. UY Scuti is part of a group of stars known as supergiants, which are characterized by their immense size and luminosity. Its study helps astronomers understand the life cycles of massive stars and the processes that lead to supernovae.
