Exoplanet mass
Exoplanet TZ Arietis c has 73.119 Earth masses (or 0.2301 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...

The planet is too cold to sustain liquid water on its surface. It is however possible that there is environment with higher temperatures on some of its potential moons.
The planet is probably a gas giant and has no surface, however life could still be possible on the potential moons orbiting it.
