How far down is the core of the Earth ?

Actually, the Earth has two cores--the inner core and the outer core. The inner core is solid and is about 5100 kilometers down (approximately 3150 miles). Surrounding the inner core is the outer core, which is believed to be liquid, and starts about 2900 kilometers below the surface of the earth (1800 miles).

Above the outer core is the mantle and above the mantle is the crust, on which we live.
