Exoplanet mass
Exoplanet HD 202206 c has 991.067 Earth masses (or 3.1185 Jupiter masses).
The mass of an exoplanet is one of the most important characteristics for understanding what kind of world it is — whether it’s small and rocky like Earth or large and gaseous like Jupiter. Mass provides key information about the planet’s composition, gravity, and formation history...

Habitability
Habitable zone of the star: 1.1 - 1.6 AU
The planet seems to be close to the outer edge of the habitable zone. It is probably very cold, but environment with higher temperatures might be possible.
The planet is probably a gas giant and has no surface, however life could still be possible on the potential moons orbiting it.
