The largest known star by diameter is UY Scuti, a red supergiant located in the constellation Scutum. Its diameter is estimated to be about 1,700 times that of the Sun. However, measurements of stellar diameters can vary, and other candidates like VY Canis Majoris also have similar estimates. These massive stars exhibit significant variability and uncertainty in their sizes due to their pulsating nature.
