Wait...is gravity proportional to mass or something? Because I must have skipped where it says 4x gravity. Just 4x the mass of Earth.
Ok, so I KIND OF answered my own question. But I still don't...yeah.
Quote:Its mass indicates that it is probably a rocky planet and has enough gravity to hold on to an atmosphere, according to Steven Vogt, professor of astronomy and astrophysics at the University of California, Santa Cruz, and one of the leaders of the team that discovered the planet.
