As an astrological planet, the Sun represents the ego or the persona of an individual, hence, the emphasis which is placed upon people's sun-signs. It should be mentioned that there is far more to astrology than the mostly execrable drivel that appears in the daily newspapers based on those signs, but, similarly, there is more to people than their personas.

Generally, the Sun was considered to be a god rather than a goddess. Sol, Apollo and Ra were all sun gods. One notable exception to this rule is Amaterasu, the Japanese sun goddess.

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.

Sun (?), n. (Bot.)

See Sunn.

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. √297. Cf. Solar, South.]


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.

⇒ Its mean apparent diameter as seen from the earth is 32′ 4″, and it revolves on its own axis once in 25⅓ 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.


Any heavenly body which forms the center of a system of orbs.


The direct light or warmth of the sun; sunshine.

Lambs that did frisk in the sun.


That which resembles the sun, as in splendor or importance; any source of light, warmth, or animation.

For the Lord God is a sun and shield.
Ps. lxxiv. 11.

I will never consent to put out the sun of sovereignity to posterity.
Eikon Basilike.

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. --

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 faculæ) as well as dark spaces (called maculæ). Called also solar spots. See Illustration in Appendix. --
Sun star (Zoöl.), any one of several species of starfishes belonging to Solaster, Crossaster, and allied genera, having numerous rays. --
