A somewhat exotic double-planet world I've been working on. It is highly hypothetical but the smaller planet, which can be considered a satellite, is relatively very massive compared to its parent. Also a bit contrived but I set them up so that the satellite could almost perfectly eclipse the parent star from the parent world's perspective. The parent star, a very hot (~5800 K) white main sequence star, is also speculative as it is highly unlikely life would ever form on a planet constantly showered with ultraviolet radiation. But the whole set up makes breath-taking scenery a common occurrence in these worlds!
