What these measurements mean

These comparisons use the reported catalog values. They are interpretations and calculations, not additional observations.

A year on this world
A 365.25-day Earth year spans about 74.1 of these orbits. This comparison uses the reported orbital period. It does not measure the planet's rotation or the length of its day.
What the mass can tell you
M sin i is a lower bound on the true mass because the viewing angle affects the radial-velocity measurement. Do not treat it as an exact mass or use it to claim a measured density.
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.
