An alloy of solid nickel and iron, mostly.
It is composed of an iron and nickel alloy, and is called the inner core.
The spherical solid core of the earth. It is an alloy composed mostly of nickel and iron.

No. The SUN's core is Hydrogen and Helium. The EARTH's core is Iron and Nickel.
The Earth's inner core is made of solid iron and nickel, like the outer core, though the outer core has MOLTEN iron and nickel for its contents.
the inner core is a solid. specifically solid nickel/iron alloy. the outer core is a liquid. specifically liquid nickel/iron alloy. both are composed of the same nickel/iron alloy. an alloy very similar to the alloy that makes up metallic meteorites.
The outer core of the Earth.
The inner core is solid and composed mostly of iron.
