A difference of 5 magnitudes is exactly a factor of 100 in flux, so one magnitude is a factor of 100^(1/5) ≈ 2.512.
Star Imibare? If stars were spread uniformly through space, all with the same luminosity, the number brighter than magnitude m would grow as 10^(0.6 m): about four times more stars for each fainter magnitude. ni OYA, i ni Gitoya, i - Impera:. Kugenzura… Na: i Agatabo in i Ibyatanzwe Imbonerahamwe:.
