UW Aquilae is a red supergiant star in the constellation Aquila – 964 times the size of our sun.[4][7]
UW Aquilae is located at about 11,000 light years away from earth,[8] and UW Aquilae's luminosity is about 144,000 times of the sun.[1][4]
Variability[edit]
UW Aquilae is a semi-regular variable star, with a surface temperature of 3,352 °C.[4]
The star is a dying red supergiant, about 10 million years old,[6] and is expected to explode into a supernova in the next 200,000 years.[2][3]
