Question	—	Binary Star System Build - Alpha Centauri I'm not sure if this site or Astronomy would be better, but I figured I would try here instead. I am attempting to create a [semi]plausible star system in Alpha Centauri for a series. The system was originally intended to have 1 habitable planet per star, but after my first couple of attempts I noti... (more)	—	about 4 years ago
Question	—	Are Orbital Rings feasible to construct in another star system? In this universe, Earth had a couple orbital rings during the construction of the colony ships that were sent to Alpha Centauri. Humanity has achieved fusion power and efficient space flight (1g acceleration on ships). For clarity, by orbital ring I mean a megastructure that has a greater circumfere...

Question	—	Is it believable to have a spaceship spin around a weight for artificial gravity? In my narrative universe, there will be ships that use a 1g acceleration for artificial gravity. However, when they are not accelerating (whether on a longer journey at a constant velocity or simply "anchored" at some random location) is it feasible for the ships to extend a weighted anchor and creat...

Question	—	How long to become a habitable planet I am creating a world for Sci Fi story in which I am trying to have two non-tidally locked earth sized planets in a binary orbit around Alpha Centauri A. The only way I can think of this happening is by a double event in which the original planet, let's say around 3 Earth masses, was struck by a 1 Ea... (more)	—	about 4 years ago
Question	—	Binary planets that are not tidally locked The story takes place in Alpha Centauri, with this binary orbiting just over 1 AU from Rigil Kentaurus. The star system will tightly packed, but following the 10 Mutual Hill Radii separation setup. The primary planet in this pair will be 1.2 Earth masses and second planet will be 0.85 Earth masses. ...
