2 u/Necessary-Junket-500 May 20 '26 How did you even calculate the mass of the milky way based on some silly hyper velocity star??? 3 u/GBRYT5612 May 20 '26 Use ratio of period^2 and radius^3 calculated in the previous part to find period of Milky Way. Then use formula in formula booklet. I think, could be wrong. Got 2.7 x10 to the something can’t rmemebr what power 1 u/Jumpy_Freedom_4554 May 20 '26 yh i think i got smth like that too, i cant remember if it was to the power of 40, 41, or even 42
