We’ve all seen charts showing the relative sizes of planets and moons compared to each other, which are cool to look at but don’t really give a sense of the comparative masses of the various worlds in our Solar System. It’s one thing to say the Earth is four times larger than the Moon, it’s entirely another to realize it’s 87 times more massive!
That’s where this new animation from astrophysicist Rhys Taylor comes in nicely.
Created for his blog “Physicists Formerly of the Caribbean” (he used to work at the Arecibo Observatory in Puerto Rico) the video takes the comparative sizes and masses of several major and minor worlds in the Solar System and pits them against Earth in a cascade of “rocky marbles.”
This is a pitched battle, of course, in that Earth is destined to come out on top in all of these comparisons — only smaller worlds were invited. Now if you want to see how Earth fares against the larger planets (and Jupiter vs. the Sun) check out Rhys’ earlier video “Blue Marbles” below:
They’re both really neat illustrations of what it means to have mass and density. Just don’t bother turning up the volume. (Pun very intended, but no, really… there’s no soundtrack.)
