The Earth's inner core is the Earth's innermost part. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 70% of the Moon's radius. It is composed of an ironânickel alloy and some light elements. The temperature at the inner core boundary is approximately 5700 K (5400 Â°C).
How Large is the Earth Compared to the Universe? or, Using the Earth to build a Road to Pluto. Let's start with how big the Earth is. Well, the average diameter of the Earth is 7926 miles, which gives it a radius of 3963 miles and a volume of 261 billion cubic miles of Earth earth (see arithmetic in the last paragraph).
