If you mean Earth's inner core:
- Radius ≈ 1,220 km (about 1.22 × 10^3 km)
- Diameter (what many people call "thickness") ≈ 2,440 km
Notes: those are seismically inferred values with small uncertainties (tens of km). The inner core is solid (mainly iron–nickel), surrounded by the liquid outer core; the core–mantle boundary lies at about 2,890 km depth, so the outer core thickness is ≈ 2,261 km.
Do you mean the inner core of a different planet or want more detail on how these numbers are measured?
