Overview
Core model: Hot Jupiters, Super-Earths & Mini-Neptunes
Exoplanet surveys revealed planetary classes that are rare or absent in the Solar System, including hot Jupiters, super-Earths, and mini-Neptunes. These categories describe broad size, mass, temperature, or orbital regimes rather than single compositions.
