Orbital period
Orbital period of exoplanet HIP 79431 b around its star is 111.7 days.
The orbital period of an exoplanet is the time it takes to complete one full orbit around its star, usually measured in days. Most of the exoplanets discovered so far have orbital periods of less than one year...

Exoplanet mass
Exoplanet HIP 79431 b has 667.605 Earth masses (or 2.1007 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: 0.16 - 0.24 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.
