What is the average density of the Earth? - Quora
WebIts mass is 4.868 × 1024 kg or 0.815 Earths and its total volume is 9.38 × 1011 km³ or 0.857 Earths. Contrary to popular belief, the size of a planet does not play any role in determining the density of the planet. Planets such as Uranus and Neptune may be large but its density is relatively small compared to its large size. WebApr 1, 2009 · The average density of Earth is 5540 kg/m3 or 5.54 g/cm3. This is found by dividing the mass of Earth 5.98×1024 kg by its volume 1.08×1021 m3. The SI standard for density is kg/m3.... birkeland current llc

WebIn comparison with the modern accepted figure of 5,515 kg·m−3, [21] the density of the Earth had been computed with an error of less than 20%. That the mean density of the Earth should so greatly exceed that of its surface rocks naturally meant that there must be more dense material lying deeper. WebJan 10, 2024 · “Density, mass, and volume It is more than seventeen times as massive as Earth. The rock, ices, and gas that make up the icy giant fill a volume of 15 trillion cubic miles (62 trillion cubic kilometers), almost 58 times the volume of Earth.
