What is "normal" anyway?

Astronomers have found multi-planet systems around a number of nearby stars, but none that's much like our own. They're not a lot like each other, either.

We still don't know what a normal planetary system looks like, or if there even is such a thing.

We highlight the disparate architectures of the highest-known multiplicity planetary systems, as well as a few systems similar to TOI-1136. We highlight that the candidate seventh planet in TOI-1136 does not have a confidently detected orbital distance. Planet and stellar radii are scaled for comparison to other systems, though we emphasize that the planet-star size is not to scale. None of the systems exhibits a clear analog to any of the others, and all have the potential for very interesting, future study. — UC Irvine

Unraveling The Mysteries Of Planet Formation And Evolution In A Distant Solar System - Astrobiology

A recently discovered solar system with six confirmed exoplanets and a possible seventh is boosting astronomers’ knowledge of planet formation and evolution.
