I have made these calculations thanks to the formulas that we have learned in class:
D=10*(m-M+5/5) where M it's the absolute magnitude and m apparent magnitude. M=2 and m=12.8
D=10*(12.8-2+5)/5)
D=10*(79/25)
D=11445 parsec.
Some researches say that the approximate distance it's of 1165,085 parsec so I think that this time my calculations have been really close.
