Exoplanet mass
Exoplanet Epsilon Cephei A Debris disk has 0.066 Earth masses, or 1.2 times the mass of Mercury.
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...
