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 lens in space

The system briefly magnified a more distant star; a planet left its own small blip in the brightening.
