What is the mass of Earth?

Answer 1

Hi. From the web : "Earth's mass is 5.976 × 10^27 g (0.2108 × 10^27 oz), being the sum of 5.974 × 10^27 g (0.2107 × 10^27 oz) for solid Earth, 1.4 × 10^24 g (0.049 × 10^24 oz) for the ocean, and 5.1 × 10^21 g (0.18 × 10^21 oz) for the atmosphere. Earth's average density is 5.518 g/cm3, which is just about double the density of the common rocks that form at Earth's surface, indicating that Earth's interior is more dense than the surface."

I edited the answer for the exponents.

Answer 2

You will note from Cirric's answer above that the solid Earth is over 1 million times the mass of the atmosphere.

I point this out because people have no concept of its size, and that when people talk about something destroying the world, they really mean the atmosphere in which we live.

Even so you will note that even the atmosphere, what we think of as "thin air", weighs 5000 trillion tonnes.

The world is bigger than most people think, yet it is a speck in the cosmos.

Answer 3

mass is around 5,974,200,000,000,000,000,000,000 kg

or 5.9742×10 to the 24th power kg
