If the apparent magnitude of the Sun is -26.7 and Sirius is -1.52, How many times brighter is the Sun than Sirius
If the apparent magnitude of the Sun is -26.7 and Sirius is -1.52, How many times brighter is the Sun than Sirius
-26.7 - (-1.52) =-25.18 apparent magnitude between the Sun and Sirius.
1 magnitude =100^1/5=2.512
2.512^25.18 =11,803,206,357x the Sun is brighter than Sirius!!.
P.S. The accurate way of comparing brightness between stars is to use "absolute magnitude". In fact, Sirius in more than 20 times brighter than the Sun if they were side by side.
