Saturn is always quaking, but it's subtle, the planet's surface moves about a meter every one to two hours like a slowly rippling lake. Like a seismograph, the rings pick up the gravity disturbances, and the ring particles start to wiggle around. Christopher Mankovich More Quotes by Christopher Mankovich More Quotes From Christopher Mankovich The fuzzy cores are like a sludge, the hydrogen and helium gas in the planet gradually mix with more and more ice and rock as you move toward the planet's center. It's a bit like parts of Earth's oceans where the saltiness increases as you get to deeper and deeper levels, creating a stable configuration. Christopher Mankovich
