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=6.58 and m=13.5
D=10*(13.5-6.58+5)/5)
D=10*(298/125)
D=242parsec.
I have found that the distance that some scientifics have calculated it's of 208 parsec so the difference is not really big at all.
