See here for a little refresher, and here for another article about Trojans). As a planet orbits a … More The Ultimate Trojan 2-star planetary system
At a Solar System party, in a room full of planets, the asteroid belt is full of angst. And it should be. It’s out of place. It’s wearing a clown outfit but it’s not a costume party. What makes the asteroid belt so different? Well, for one, it’s not just one object like each individual … More The chaotic teenage Solar System
