orbital time is 22 h and 50 min.
how can I rcalculate mssan for Io? The mass fore Jupiter is [tex]318\cdot 5,98\cdot 10^24 [/tex]
totally mean distance from Jupiter to Io is:
[tex]\frac{T^2}{r^3}=\frac{4\pi ^2}{GM}\rightarrow r^3=\frac{T^2GM}{4\pi ^2}\\= r= \sqrt[3]{\frac{T^2GM}{4\pi ^2}}[/tex]
now I can calculate the radius of jupiter. but i don't now how i can calculate the mass fore Io
