Mar 31, 2024 · According to NASA, Earth's mass is 5.9722×1024 kilograms, or around 13.1 septillion pounds. This equates to around 13 quadrillion of Egypt's pyramid of Khafre, which itself weighs around 10...
Sep 15, 2023 · It would be more proper to ask, "What is the mass of Earth?" The quick answer to that is approximately 6,000,000,000,000,000,000,000,000 (6 x 1024) kilograms. The interesting sub-question is, "How did anyone figure that out?" It's not like the planet steps onto the scale each morning before it takes a shower.

The current best estimate for the mass of Earth is M🜨 = 5.9722×1024 kg, with a relative uncertainty of 10−4. It is equivalent to an average density of 5515 kg/m3. Using the nearest metric prefix, the Earth mass is approximately six ronnagrams, or 6.0 Rg.
3 days ago · Earth is the third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its near-surface environments are the only places in the universe known to harbour life.
Earth's mass is approximately 5.97 × 10 24 kg (5,970 Yg). It is composed mostly of iron (32.1% by mass), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%), with the remaining 1.2% consisting of trace amounts of other elements.
