WebSirius is only 8.6 light years away from Earth and is the 7th nearest star to our Solar System. One of the reasons it appears so bright is because it is one of the closest stars to us. Sirius A has a diameter that is almost 171% of the Sun’s diameter. It is around 25 times brighter than our Sun and has a mass 2.02 times that of the Sun. 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.
