WebAs long as that is true, the basic technique works. Now, the distance from the earth to the sun varies from about .98 AU to 1.02 AU, so using 1 AU is at least 98% accurate for the length of the adjacent side. Since it is just a multiplicative factor, this translates to at least 98% accuracy for the final answer, regardless of distance. WebSirius has an absolute magnitude of +1.5, so it is actually more luminous than the Sun.
