What these measurements mean
These comparisons use the reported catalog values. They are interpretations and calculations, not additional observations.
- What the mass can tell you
- Mass describes how much material the planet contains. Inspect the published uncertainty and reference before combining it with a radius to estimate density. Catalog values can come from different studies.
- Temperature has limits
- Equilibrium temperature describes a model of absorbed and emitted energy, not a measured surface temperature. Atmosphere and reflectivity affect the interpretation. This value alone cannot establish liquid water, a habitable surface, or life.
