Outside the habitable zone

Masses found by the wobble method are minimums, because the orbit's tilt is unknown. Temperatures are equilibrium estimates for a bare planet, before any atmosphere.

How we know

A direct picture

The star's glare is blocked or subtracted, leaving the planet's own faint light as a dot that moves along its orbit over the years.
