[6] Despite this, it is located in the inner regions of the system's habitable zone, since Gliese 876 is such an intrinsically faint star.

Using this method, the inclination of the orbit can be determined, revealing the planet's true mass to be 0.72 times that of Jupiter.

Since it was detected indirectly through its gravitational effects on the star, properties such as its radius, composition, and temperature are unknown.

Assuming a composition similar to Jupiter and an environment close to chemical equilibrium, the planet is predicted to have a cloudless upper atmosphere.

While the prospects for life on gas giants are unknown, it might be possible for a large moon of the planet to provide a habitable environment.
