The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields.[12][13] It has a diameter of about 1,392,684 km,[5] about 109 times that of Earth, and its mass (about 2Ă—1030 kilograms, 330,000 times that of Earth) accounts for about 99.86% of

the total mass of the Solar System.[14] Chemically, about three quarters of the Sun’s mass consists of hydrogen, while the rest is mostly helium. The remainder (1.69%, which nonetheless equals 5,628 times the mass of Earth) consists of heavier elements, including oxygen, carbon, neon and iron, among others.

Inner Core

Planets

The inner core of the Earth, its innermost part, is a primarily solid ball with a radius of about 1,220 km (760 mi), according to seismological studies.[1] [2] (This is about 70% of the length of the Moon’s

radius.) It is believed to consist primarily of an iron–nickel alloy, and to be about the same temperature as the surface of the Sun: approximately 5700 K (5430 °C).

For the inner core, a gold foil is applied to represent the molten iron core.
