    Hi everyone,
    I realize this is off topic, but how do you calculate the sun's apparent
    magnitude at any given distance? Or, to turn the question around, how do
    you find out at what distance the sun appears a particular apparent
    I know that if anyone could tell me, this would be the place to ask since
    satellite magnitudes depend on size, distance. If this helps, the sun's
    luminosity is 3.9x10 to the 26th W (watts).
    Thank you for your help.
    Best regards,
