Which planet in the solar system has a mass which is 318 times that of the earth?
"depletion period that brought the asteroid belt down close to its present mass is thought to have followed when Jupiter and Saturn entered a temporary 2:1 orbital resonance (see below). The inner Solar System's period of giant impacts probably played a role in the Earth acquiring its current water content (~6 kg) from the early asteroid belt. Water is too volatile to have been present at Earth's formation and must have been subsequently delivered from outer, colder parts of the Solar System. The water was probably delivered by planetary embryos and small planetesimals thrown out of the asteroid belt by"

"Earth's radius, slightly larger than that of the planet Jupiter. However, it is up to 10 times more massive (about 3,180 Earth masses), based on observations of its candidate moon. This puts it just below the deuterium-fusing limit, which is around 13 Jupiter masses. Any more massive and Kepler-1625b would be a brown dwarf. Because of this high mass and radius, the planet likely has a very strong gravitational pull, with a surface gravity calculated to be up to 22.08 times that of Earth. It is also very dense at up to 10.15 g/cm. Unlike the gas giants in our"
