How many miles to the earth's core?

Geologists have long known that Earth’s core, some 1,800 miles beneath our feet, is a dense, chemically doped ball of iron roughly the size of Mars and every bit as alien. read more

Finally, the scientists extrapolate their data from 200 GPa to 330 GPa, giving a final estimate of 6230 ± 500 Kelvin (5957 ± 500C, 10755 ± 932F) at the inner core boundary. The temperature at the actual core of the inner core — the center of the Earth — is probably even hotter. read more

The distance between the Earth's crust to the Earth's core is approximately 3,958 miles. Of this distance, the crust only makes up approximately 21 miles. Between the crust and the outer core is the mantle, which spans a distance of 1,774 miles. read more
