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
UW Aquilae is a semi-regular variable star, UW Aquilae's surface temperature is 3,352 °C[4].In the next 200,000 years, UW Aquilae will explode into a supernovae [2][3]
UW Aquilae is a dying red supergiant star, and is about 10 million years old.[6]
