What are the names of Santa's 12 reindeers? It’s a mystery that has puzzled generations of scientists: At the very center of our planet, within a liquid outer core, is a Pluto-sized orb of solid iron. The inner core is the Earth's deepest layer, and it is a solid iron ball that is approximately 1,500 miles in diameter. The Earth's inner core is thought to be slowly growing as the liquid outer core at the boundary with the inner core cools and solidifies due to the gradual cooling of the Earth's interior (about 100 degrees Celsius per billion years). Around the core is the mantle, and near the planet's surface is a thin crust — the part that breaks now and then and creates earthquakes. By creating conditions akin to the center of the Earth inside a laboratory chamber, researchers have improved the estimate of the age of our planet's . Improve this question. New melting data on iron to pressures of the outer core (2 Mbar) and the observed strong decrease of eutectic melting depression in the Fe-FeO-FeS system with increasing pressure, however, tightly constrain the temperature at the inner-core boundary to slightly less than 5000 K. This estimate can be reconciled with all recent static melting measurements on iron and lays within the uncertainty . "The temperature of the core is an incredible 20 million degrees centigrade" 20,000,000 K: The determination of the sun's temperature has been one of the most difficult problems in solar astronomy. It is a solid metallic ball made mainly of iron. The inner core has an estimated radius of 1,220 km, while the outer core extends beyond it to a radius of about 3,400 km.
