It is 1300km and consists of mainly iron and nickel.
in the outer core it has a 6960 km.While the inner core is about 2440 km. in diameter
The upper core of Earth, also known as the outer core, has a thickness of approximately 2,200 kilometers. It is a layer of molten iron and nickel that surrounds the solid inner core.
The inner core of the Earth is approximately 1,200 kilometers (745 miles) thick. It is a solid metal sphere primarily composed of iron and nickel at extreme temperatures and pressures. The inner core is surrounded by the liquid outer core.
The radial thickness of the inner and outer core is equal to 3,486 km (2,166 miles). The mantle is 2,885 km (1,793 miles) thick. As such the inner and outer core combined is 601 km (373 miles) thicker than the mantle.
The inner core of the Earth is a solid iron-nickel alloy with a radius of about 1220 kilometers. It is the densest layer of the Earth and produces the planet's magnetic field through the movement of molten iron in the outer core. The inner core is believed to have formed as a result of solidification of the outer core due to decreasing temperatures and increasing pressure.

The thickness of the inner core is 1,200 km. 1,200 km being the radius of the sphere known as the inner core.
the thickness of each part is the mantle, the inner core, and inner core

The upper core of Earth, also known as the outer core, has a thickness of approximately 2,200 kilometers. It is a layer of molten iron and nickel that surrounds the solid inner core.
The Earth's inner core is significantly thicker than the crust. The crust varies in thickness, typically ranging from about 5 to 70 kilometers, depending on whether it is oceanic or continental. In contrast, the inner core has a radius of about 1,220 kilometers. Thus, the inner core is much thicker than the Earth's crust.
