All the planets remain roughly where they formed, in circular orbits in the same plane.

Drake multiplied the number of sunlike stars in our galaxy that form each year by a handful of variables: the fraction of those stars that have planets; the number of planets per planetary system where life could exist; the fraction of habitable planets where life actually arises; the fraction of those where intelligence emerges; the fraction of intelligent species that develop interstellar communication; and finally, the average length of time that those communicating civilizations survive.

Kilonovas are predicted to form such elements in abundance, spraying them out into space where they could become part of future generations of stars and planets.

Researchers used to think that planets stayed where they initially formed, but the existence of hot Jupiters suggests that orbits often shift radically during the early life of a planet.
