Europa, a moon of Jupiter has an orbital diameter of 1.34x10^9m and a period of 3.55 days. What is the mass of Jupiter?
T=3.55days = 30672s
I got m=2.56x10^27
But I don't think this is correct when I looked up the mass of jupiter it was actually 1898.6x10^24kg. What did i do wrong? I can't figure it out. Thanks in advance for your help.
