The inner core of the Earth is primarily composed of iron and nickel and is solid due to the extreme pressure found at that depth. It has a temperature estimated to be around 5,000 to 7,000 degrees Celsius (9,000 to 12,600 degrees Fahrenheit), similar to the surface of the Sun. The inner core is about 1,220 kilometers (760 miles) in radius and rotates at a slightly different speed than the outer layers of the Earth, contributing to the planet's magnetic field.
