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:
“Nor shall you scare us with talk of the
death of the race.
How should we dream of this place without us?—
The sun mere fire, the leaves untroubled about us,
A stone look on the stone’s face?”
—Richard Wilbur (b. 1921)
“... the first step of the terrible journey toward feeling somebody should act, that ends in utter confusion and hopelessness, east of the sun and west of the moon.”
—John Ashbery (b. 1927)
“Nights, I squat in the cornucopia
Of your left ear, out of the wind,
Counting the red stars and those of plum-color.
The sun rises under the pillar of your tongue.”
—Sylvia Plath (1932–1963)
