Nov 17, 2020 · The center of the Earth is almost as hot as the surface of the Sun, about 9,800 degrees Fahrenheit, with pressure that makes the compressive forces at the ocean floor look like child’s play. But we haven’t been to any of these places inside the Earth.
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth’s radius or 70% of the Moon 's radius.
Oct 6, 1997 · We know that the earth's core depths from 2,886 kilometers to the center at 6,371 kilometers (1,794 to 3,960 miles), is predominantly iron, with some contaminants. How?

May 1, 2024 · Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly solid mantle . The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles).
Oct 9, 2023 · The center of the Earth is almost 4,000 miles (6,400 kilometers) beneath our feet. To put that into context, the deepest humans have ever drilled is 7.6 miles (12.2 km) down, and it took...
At the very center, with a radius of about 1,227 kilometers (762 miles) is the inner core – the densest part of our planet, a solid ball mostly composed of iron and nickel, comprising less than 1 percent of Earth's volume.
