the anwer is that it is 3160 miles
From the Earth's crust to the inner core is about 3,950 miles.
To be precise, there is actually an outer core and an inner core. You can find the details in the Wikipedia article "Structure of the Earth".
it is about 29 million kilometers apart
The solid inner core extends from 3160 miles (5150 km) to 3977 miles (6400 km) below the surface.The center point of the Earth lies at an average depth of 3977 miles (6400 km) from the surface.
Approximately 5150 km (3,160 miles).
Approximately 3,960 miles from the surface of the Earth to the center.
The Inner core is the last layer in the earth surface and is what gives the earth its magnetic field. the outer core is liquid nickel and iron but the inner core is 80% solid iron and 20% solid nickel,gold,platinum, and uranium. the inner core is so far in the earth surface we can not reach it we can tell its there by seismic waves.
3160 miles-mantle to inner core.
There is a center of the earth but we cannot travel to it like they do in books and movies. The center of the earth is made of an iron core, which creates the phenomenon of magnetization. The center of the earth is far too hot and strong to get to.
It's approximately (3,963)miles down to the earths core.
The mantle contains the bulk of Earth's rock, far surpassing the crust. The outer core is a liquid, and therefore would not be considered rock. The inner core is a metallic alloy, primarily of iron and nickel, and although it could be considered a rock, as it is solid and comprised of minerals, it still has a mass less than that of the mantle.
Mankind never saw the Earth's core.
