2021年12月20日 · Mass (10 24 kg or 10 21 tons) - This is the mass of the planet in septillion (1 followed by 24 zeros) kilograms or sextillion (1 followed by 21 zeros) tons. Strictly speaking tons are measures of weight, not mass, but are used here to represent the mass of one ton of material under Earth gravity.

2015年7月17日 · Mass - This is the mass of the planet compared to the mass of the Earth. Diameter - The diameter of the planet at the equator, the distance through the center of the planet from one point on the equator to the opposite side, compared to Earth.
