UY10

UY10 is a red supergiant star located in the constellation Cassiopeia. It is one of the largest known stars in the universe, with a radius approximately 1,700 times that of the Sun. This makes it one of the largest stars known, although it is not the largest in terms of mass. UY10's mass is estimated to be around 30 to 70 times that of the Sun. The star is also one of the most luminous known, with a luminosity that can reach up to 340,000 times that of the Sun. Its distance from Earth is approximately 9,500 light-years. UY10 is a variable star, meaning its brightness fluctuates over time. It is classified as a semiregular variable, which means its brightness changes in a somewhat irregular pattern. The star is also notable for its cool surface temperature, estimated to be around 3,300 Kelvin. UY10 is a relatively young star, with an estimated age of around 3 to 5 million years. It is expected to end its life as a supernova in the relatively near future, although the exact timeline for this event is uncertain. The star is named after the University of Arizona, which was involved in its discovery. UY10 is a fascinating object of study for astronomers, providing insights into the late stages of stellar evolution and the processes that lead to supernova explosions.
