Orbital period
Orbital period of exoplanet Gliese 649 b around its star is 600.1 days (or 1.6 years).

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... icon More about Orbital period in StellarGuide

Exoplanet mass
Exoplanet Gliese 649 b has 82 Earth masses (or 0.2581 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... icon More about Exoplanet mass in StellarGuide

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.
