Where is the outer core thickness?
Earth's outer core is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface.
Can humans go to the outer core?
Humans have not been able to travel more than a few miles beneath Earth's surface because of the intense heat and pressure. For the same reasons, humans have not been able to travel into the mantle. Temperatures in the mantle range from 1600 degrees Fahrenheit at the top to 4000 degrees Fahrenheit near the bottom.
