Habitability
Habitable zone of the star: 1.3 - 1.9 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.
