Astronomy 2021A/B Lecture Notes - Galilean Moons
Document Summary
4 largest moons of jupiter were found by galileo (galilean moons) Saturn"s largest moon was found by huygen. Slide 14: these moons are formed in a smaller but very similar way to how planets were formed. Jovian moons still have rock but because they are further from the sun, they have ice. Slide 18: triton might have been caught, and in that process tossed its own moons releasing excess energy and getting caught in neptune"s orbits in a backwards direction. Slide 19: we cannot see the back side of the moon since its rotation is synchronized with earth"s orbit, causing it to always face us. Slide 21: the axis that the moon is on causes stronger gravitational forces and creates high tides on both the left side and right side of the earth. Slide 29: io still has volcanism and hasn"t cooled down because of tidal heat.
