What your favorite moon, /sci/? Io is pretty neat.

Tidal effects. Having a varying gravitational pull on a large massive body creates internal stresses and keeps the core hot. If a planet were to get really close to its star, for example, it will tend to be pulled apart by the differential pull of gravity. I imagine having 6 planets move in and out every few days would result in some rather spectacular volcanic activity. Cores made of metallic elements produce magnetic fields due to intense eddy currents caused by the flow.

A good example of internal activity caused by tidal effects are the moons of the gas giants. Io is basically a constantly boiling ball of rock and ice due to its close orbit to Jupiter and stresses from all the other moons.

What's the smallest planet/moon we can walk on without being "aware" of its roundness?

I was reading about Io and when I found out how small it was it made me wonder, how small can an object become before we feel we're on something around?

>Io is the innermost of the four Galilean moons of the planet Jupiter and, with a diameter of 3,642 kilometres
