It’s pretty rare for a planet to be livable... - Deepstash

It’s pretty rare for a planet to be livable on in general, because several things have to come together:

  1. The distance to a star must be perfect. If it’s too close, the surface burns, if it’s too far away, the planet will be iced over.
  2. The planet has to keep out cosmic radiation by building the right atmosphere.
  3. A moon has to keep the planet’s gravity in check, so that it can spin at the right speed and angle.
  4. All of these events have to line up in the right order and timeline.
