Jupiter is the largest planet in the solar system if it had been about 100 times more massive, Jupiter might have evolved into a star and our solar system would have had two suns many stellar systems in our galaxy contain two or even more stars. Orbiting the Sun beyond the asteroid belt, Jupiter with its set of at least sixteen orbiting satellites is the center of a small planetary system. The giant planet has a volume 1300 times greater than the Earth, but its near-surface layers are composed mostly of gases swirling in complex patterns. Jupiter and its moons form a planetary group of incredible beauty (Figure 9.1). It did say the resonance is "locked".īleh that's enough early morning phone researching for me, imma go start me day and get out of bed.Chapter 9: The Jupiter System 9.0 Introduction I'm not sure if this locks their orbital distance or not or if they could all shift together. The wiki article on orbital resonance does refer to Jupiter's moons as an example of a stable system. Eventually they get caught in orbital resonance, which makes the orbits eccentric, which cause tidal forces that cause volcanic activity. I did find one page suggesting that maybe the moons once had closer orbits. I can't find anything on the long term scale and which if any of these forces is winning. Or in a sense, volcanic activity on io is actually slowing the rotation of Jupiter. So it seems the forces are fighting each other. However the moons in question orbit Jupiter slower than its day, so they would under go tidal acceleration. The eccentricity of the orbit is what causes the volcanic activity.Ĭommon sense would tell us that since the energy of the volcanos is coming from gravity, there would be a decay. The wiki article on io says if it wasn't for the orbital resonance with the other moons ios orbit would eventually circle out and the volcanic activity would go away. I can't seem to find it saying io is decaying anywhere. We make our world significant by the courage of our questions and by the depth of our answers.
