There are several methods by which one can calculate the mass of the sun.
One of my favourites is the one from Time period of Earth around Sun's revolutionary orbit.
T^2 = 4π^2/GM * ( r^3)
Mind me this expression is also, what we call as the Kepler's Third Law of Planetary motion.
Can be used
Where T = 365.6 days
to be put in SI units so convert first into seconds.
Then G is the universal gravitational constant
M is the mass of sun
r is the distance of earth centre to Sun's centre
Everything has to be put In Standard International units and you'll get the answer in Kilograms.
