WebThe Sun is classed as 'G' star, with a temperature of about 5,800 °K. (When talking about the temperature of stars, we usually use the unit 'Kelvin' - 5,800 °K is about 5,500 °C.) The hotter stars are usually much less common than the cooler, redder ones. For example 'O' type stars make up only 1 in every 3 million stars we see. WebWe finally turn to compute the luminosity of these two stars as perceived on the earth. The formula is: L p = L ⋅ d 2 r 2 Here, r is the radius of the star, while d is the distance of …
