Sun
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. It has a diameter of about 1,392,684 km, about 109 times that of Earth, and its mass (about 2×1030 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System. 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.

“A feme may come, leaf-green,
Whose coming may give revel
Beyond revelries of sleep,
Yes, and the blackbird spread its tail,
So that the sun may speckle,
While it creaks hail.”

Copper sun or scarlet sea,
Jungle star or jungle track,
Strong bronzed men, or regal black
Women from whose loins I sprang
When the birds of Eden sang?”
