What is the mass of the earth?

The current best estimate for Earth mass is M ⊕ =(5.9722±0.0006)×1024 kg. Earth mass is a standard unit of mass in astronomy that is used to indicate the masses of other planets, including rocky terrestrial planets and exoplanets. read more

Earth mass (M ⊕, where ⊕ is the standard astronomical symbol for planet Earth) is the unit of mass equal to that of Earth. The current best estimate for Earth mass is M ⊕ = 5.9722 × 10 24 kg, with a standard uncertainty of 6 × 10 20 kg (relative uncertainty 10 −4). read more

You could also say the Earth’s mass is 5.9 sextillion tonnes. Phew, that’s a lot of mass. That sounds like a lot, and it is, but the Earth has a fraction of the mass of some other objects in the Solar System. read more

The mass of the oceans is approximately 1.35 × 10 18 metric tons or about 1/4400 of Earth's total mass. The oceans cover an area of 361.8 million km 2 (139.7 million sq mi) with a mean depth of 3,682 m (12,080 ft), resulting in an estimated volume of 1.332 billion km 3 (320 million cu mi). read more
