Sun \Sun\, n. [OE. sunne, sonne, AS. sunne; akin to OFries.
   sunne, D. zon, OS. & OHG. sunna, G. sonne, Icel. sunna, Goth.
   sunna; perh. fr. same root as L. sol. [root]297. Cf. Solar,

   1. The luminous orb, the light of which constitutes day, and
      its absence night; the central body round which the earth
      and planets revolve, by which they are held in their
      orbits, and from which they receive light and heat. Its
      mean distance from the earth is about 92,500,000 miles,
      and its diameter about 860,000.
      [1913 Webster]

   Note: Its mean apparent diameter as seen from the earth is
         32' 4[sec], and it revolves on its own axis once in
         251/3 days. Its mean density is about one fourth of
         that of the earth, or 1.41, that of water being unity.
         Its luminous surface is called the photosphere, above
         which is an envelope consisting partly of hydrogen,
         called the chromosphere, which can be seen only through
         the spectroscope, or at the time of a total solar
         eclipse. Above the chromosphere, and sometimes
         extending out millions of miles, are luminous rays or
         streams of light which are visible only at the time of
         a total eclipse, forming the solar corona.
         [1913 Webster]

   2. Any heavenly body which forms the center of a system of
      orbs.
      [1913 Webster]

   3. The direct light or warmth of the sun; sunshine.

   4. That which resembles the sun, as in splendor or
      importance; any source of light, warmth, or animation.
      [1913 Webster]

   Sun and planet wheels (Mach.), an ingenious contrivance for
      converting reciprocating motion, as that of the working
      beam of a steam engine, into rotatory motion. It consists
      of a toothed wheel (called the sun wheel), firmly secured
      to the shaft it is desired to drive, and another wheel
      (called the planet wheel) secured to the end of a
      connecting rod. By the motion of the connecting rod, the
      planet wheel is made to circulate round the central wheel
      on the shaft, communicating to this latter a velocity of
      revolution the double of its own. --G. Francis.

      disk, consisting commonly of a black central portion with
      a surrounding border of lighter shade, and usually seen
      only by the telescope, but sometimes by the naked eye.
      They are very changeable in their figure and dimensions,
      and vary in size from mere apparent points to spaces of
      50,000 miles in diameter. The term sun spots is often used
      to include bright spaces (called faculae) as well as dark
      spaces (called maculae). Called also solar spots. See
      Illustration in Appendix.

The Jargon File (version 4.4.7, 29 Dec 2003):

Sun
 n.

    Sun Microsystems. Hackers remember that the name was originally an acronym,
    Stanford University Network. Sun started out around 1980 with some hardware
    hackers (mainly) from Stanford talking to some software hackers (mainly)
    from UC Berkeley; Sun's original technology concept married a clever board
    design based on the Motorola 68000 to BSD Unix. Sun went on to lead the
    workstation industry through the 1980s, and for years afterwards remained
    an engineering-driven company and a good place for hackers to work. Though
    Sun drifted away from its techie origins after 1990 and has since made some
    strategic moves that disappointed and annoyed many hackers (especially by
    maintaining proprietary control of Java and rejecting Linux), it's still
    considered within the family in much the same way DEC was in the 1970s
    and early 1980s.

Easton's 1897 Bible Dictionary:

Sun
   (Heb. shemesh), first mentioned along with the moon as the two
   great luminaries of heaven (Gen. 1:14-18). By their motions and
   influence they were intended to mark and divide times and
   seasons. The worship of the sun was one of the oldest forms of
   false religion (Job 31:26,27), and was common among the
   Egyptians and Chaldeans and other pagan nations. The Jews were
   warned against this form of idolatry (Deut. 4:19; 17:3; comp. 2
   Kings 23:11; Jer. 19:13).
