Interesting fact: The Earth's core generates the planet's magnetic field, which protects life from harmful solar radiation.
The answer: The Earth's core weighs approximately 1.9 x 10^24 kilograms (about 2.1 x 10^24 US tons).
The Earth's core is composed mainly of iron and nickel and is divided into a solid inner core and a liquid outer core. It extends from about 2,900 kilometers below the surface to the planet's center at 6,371 kilometers. Despite its relatively small volume compared to the whole Earth, the core accounts for about one-third of Earth's total mass due to its high density.
