Sharing a recent side project of mine, the Atlas of Space, that I built out to explore the Solar System.\n\nAs a long-time space nerd, I realized recently that I didn't have a good intuition on the scale, speed, and relative orientation of the celestial bodies around us. So over the break I built out a kind of spatial Wikipedia to click around and learn about planets, moons, asteroids, and other bodies orbiting the Sun.\n\nThe physics is all simulated in the browser using simple Newtonian mechanics.
