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.
