Habitability verdict · Starting criteria

Potentially habitable

Meets our starting size and starlight criteria. Water, atmosphere, and life are not confirmed.

Habitable-zone position

Within the reference habitable zone

Its starlight falls within our reference range. With a suitable atmosphere and pressure, surface liquid water could be possible; this does not confirm water or life.
