Habitability
Habitable zone of the star: 0.01 - 0.02 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 bigger than Earth and smaller than Neptune. Its average density 1497 kg/m3 points to a gas planet. There could be habitable moons in orbit.
