I suppose this is a two-part question: ju... (more)	—	over 6 years ago
Question	—	Temperatures in an eccentric orbit? We see plenty of seasonal variation on Earth, due to the large axial tilt, but the Earth follows an almost perfectly circular orbit, so we don't get much variation as a result of that. What if we had a planet with similar axial tilt, similar conditions, etc., but in an eccentric orbit? What will tha... (more)	—	over 7 years ago
Question	—	Two planets in a stable horseshoe orbit? We've seen questions about multiple planets in a single orbit before, using Lagrangian points, through orbiting each other as they go around, etc. I'm looking at the creation of a hypothetical system with two habitable planets orbiting their star in a stable horseshoe orbit. To sum up a horseshoe or... (more)	—	over 7 years ago
