# What is the mass of Io?

Io (the moon of Jupier) has a mass of 8.9319×1022 kg

### What is the gravitational force of Jupiter on Io?

F(tidal)=G(2M1m2/r3)deltaR where G = 6.67x10-11 M1= Mass of heavier object m2= mass of smaller object r= distance between the center of objects 1 and 2 Mass of Jupiter = 1.90x1027 Mass of Io = 8.93x1022 r = 4.22x105 Edit: This answer doesn't answer the question, unfortunately. The question isn't about tidal forces. I'll answer it later if I have time. OK, now here's the answer. I calculate the force to be about 0.71 newtons per…
