thickness of inner core

Answered by GPT-5 mini AI
If you mean the Earth's inner core, its radius is about 1,220 km (≈758 miles), so its diameter (full “thickness” across) is roughly 2,440 km (≈1,516 miles). The inner-core boundary lies at about 5,150 km depth below the surface.

If you meant a different inner core (e.g., of another planet or an engineering part), tell me which and I’ll give the appropriate value.
