Now I'm first year in university so we learn physics as compulsory subject though the main subject is engineering. It was only two month but in hight school, I learned Newton's gravitational law but with some contant like mass of the sun and astronomical unit we weren't taught how to...
The other ways used to caculate the mass of the sun do not use AU.
My homework is how to determine to distance to Sun from Earth, using gavitionval law is one of those ways to measure it. However, using gravitational law requires Sun's Mass and I don't know how to caculate the mass of the Sun...
1/ when serching for mesurement Earth-Sun distance, I got this
in the sechon answer, to use this method, we need mass of the Sun but when I searched for Sun' mass http://en.wikipedia.org/wiki/Solar_mass

there are the other ways to caculate Sun...
