The star Epsilon UMa, or more commonly known as Alioth
... and the approximate surface temperature ranges from 7,500 to 11,000 degrees Kelvin. The average luminosity of these stars is around 80 solar luminosity (1 solar luminosity equaling 3.83 x 1033 ergs/s), the average mass is approximately 3.2 solar masses (1 solar mass equaling 1.989 x 1030 kg) and the ...
