  Sun - MSN Encarta
The Sun is an average star—its size, age, and temperature fall in about the middle of the ranges of these properties for all stars.
The Sun is much closer to Earth than any other star is. The Sun’s nearest stellar neighbor, Proxima Centauri (part of the triple star Alpha Centauri), is 4.3 light-years from our solar system, meaning light from Proxima Centauri takes 4.3 years to reach the Sun.
Within the heliosphere, the Sun provides most of the heat and light that are present, and the particles in the solar wind interact with the planets and satellites in the solar system.

 sun - Definitions from Dictionary.com
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.

 The Sun
Giver of warmth and life, we hardly think of the Sun as a star, the term "Sun and stars" in constant use, though the surmise that it is a star goes back to ancient times.
The Sun is the reference to which all other stars are compared, their diameters in solar diameters, their brightnesses in solar luminosities.
A model of the Sun shows its nuclear fusing core (where hydrogen is turned into helium by the conversion of mass into energy), an envelope where energy is transferred by radiation, and an outer layer where convection (the rising of hot gases, falling of cool gases) rules.

 The Sun - Introduction
The photosphere is slightly different from one place on the Sun to another, but in general is has a pressure about a few hundredths of the sea-level pressure on Earth, a density of about a ten-thousandth of the Earth's sea-level atmospheric density, and a temperature in the range 4500-6000 Kelvin.
Because of this high temperature, the bulk of the radiation from the corona is emitted at ultraviolet and X-ray wavelengths.
It is a natural consequence of the Sun being so hot - the corona gas has too much energy to be gravitationally bound to the Sun.

 SPACE.com -- Sun's Output Increasing in Possible Trend Fueling Global Warming
Confounding efforts to determine the Sun's role is the fact that its energy output waxes and wanes every 11 years.
Long-term: A previous study showed that changes in the Sun's output appear to be related to temperatures on Earth, based on studies of tree rings, sunspots and other data.
Separate records of sunspots, auroral activity (the Northern Lights) and terrestrial deposits of certain substances generated in atmospheric reactions triggered by solar output, suggest the Sun was persistently active prior to the onset of this Little Ice Age, as scientists call the event.
