- Udo 10y agoI tried some calculations to answer that (https://news.ycombinator.com/item?id=12589228 https://news.ycombinator.com/item?id=12589228). Just taking into account the parent body, Mercury should experience a much more pronounced variation in its tidal gradient than does Io. However, I suspect it's the interaction with the other moons that make up for it in Io's case.
- leojg 10y agoYeah, now I recall that Io huge volcanic activity is thought to be because is squashed and pulled by Jupiter in one side and the other moons in the other
