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.

    The sun is but a morning star

    the sun blew out of sight
    like a red picture hat....
    Anne Sexton (1928–1974)

    We laugh at him who steps out of his room at the very moment when the sun steps out, and says: “I will the sun to rise”; and at him who cannot stop the wheel, and says: “I will it to roll”; and at him who is taken down in a wrestling match, and says: “I lie here, but I will that I lie here!” And yet, all laughter aside, do we ever do anything other than one of these three things when we use the expression, “I will”?
    Friedrich Nietzsche (1844–1900)
