Real-life Sci-Fi World 14: A horseshoe planetary system
One star. Two planets share an orbit, with one following a horseshoe-shaped path around the other. Boom!

Welcome to what might very well be the culmination of the Building the Ultimate Solar System series. Teaser: the system built in this post could also be called the Ultimate Engineered Black Hole Eyeball Ringworld Solar System (if you’re really not into the whole brevity thing). Our Solar System has one habitable planet. A few…
The Black Hole Ultimate Solar System
What happens when the central body in a planetary system is replaced with a million-Sun black hole?

Giant planet moons are among the innocent bystanders swept up in the chaos. Giant planets around other stars have different orbits…
