It's colour.
Measure the color of the light coming from the star. Blue, yellow, red and white hot stars have different amounts of energy on their surface and ergo different temperatures. This is the principle of a no contact (infrared)thermometer.
Scientists can determine the surface temperature of a star by measuring its color. (To do this quantitatively, they commonly use three filters that transmit light in three different wavelength ranges. Then they take the ratio of the intensity of the light that gets through, say, the shortest wavelength filter to the intensity of the light that gets through the medium wavelength filter.)
Alioth, also known as Epsilon Ursae Majoris in the Bayer naming system, has a spectrum designated as A0, which means it is it a hot white star. Its distance is listed as 81 light-years. The surface temperature for A0 is 11,000 degrees K.
Your can tell the general temperate of a star, visibly, by noting its color.
Schedar (Alpha Cassiopeiae) is a K0 star and has a temperature of about 4,530 Kelvin
Because of the colour spectrum they emit.
Blue is hot whereas red is cooler.
colour.
red - cool
blue - very hot
think of heating a piece of metal, it goes from red to orange to white to blue the hotter it gets.
The color of a star can determine its temperature.
Red is the coolest.
Blue is the hottest.
Yellow is in the middle.
By its color.
The Surface temperature of Alioth is 9,400°K which is 16460.33°F . Hope this helps! (:
9,400° Kelvins, or 16460.33°Fahrenheit
Alioth is a white star nearing the end of it's main sequence. Hope this helps! (:
About 7900 degrees Celsius, surface temperature.

the surface of the star.
The brightest star in Ursa Major is a star called Alioth.
Epsilon Ursae Majoris (Alioth) is the brightest star in the constellation Ursa Major (Big Dipper).It has a spectral class of A0 which means it is a white to white-blue star.
The star, Alioth, in the big dipper (Which is the "tail" in the constellation Ursa Major) is approximately eighty light years from Earth.
Epsilon Ursae Majoris (Alioth) is the brightest star in the constellation Ursa Major.It is about 3.7 times larger than our Sun.
