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.

Famous quotes containing the word sun:
“I’ll tell you how the Sun rose—
A Ribbon at a time—”
—Emily Dickinson (1830–1886)
“a feller is a-feelin’ at his best,
With the risin’ sun to greet him from a night of peaceful rest,
As he leaves the house, bare-headed, and goes out to feed the stock,
When the frost is on the punkin and the fodder’s in the shock.”
—James Whitcomb Riley (1849–1916)
