  • For example, in a planetary system around a star with solar metallicity, do the dynamics of formation lead to rather a lot of ~Earth mass planets+Luna mass moons+Jovian mass gas giants, all nicely spaced goldilocks zone, screening, etc?

  • Now a part of this estimate, an priori assumption is also used based on the existence of a band in the galaxy with stars that have statistically an optimal metallicity elements higher in atomic number than helium that is about 10% of the galaxy.
