Can anyone help me get my head around this one?(adsbygoogle = window.adsbygoogle || []).push({});

A star with a parallax angle of pi = 10 millisecs and has apparant magnitude of V= 10.2

How can I determine absolute magnitude:

I have the formula M=v -5logd -5 +A which can be ignored.

d=1/pi but I am always determining d which is less than that of the sun's distance!

Thanks Red
