(often initial capital letter) the star that is the central body of the solar system, around which the planets revolve and from which they receive light and heat: its mean distance from the earth is about 93 million miles (150 million km), its diameter about 864,000 miles (1.4 million km), and its mass about 330,000 times that of the earth; its period of surface rotation is about 26 days at its equator but longer at higher latitudes.

the star at the centre of our solar system. It is a gaseous body having a highly compressed core, in which energy is generated by thermonuclear reactions (at about 15 million kelvins), surrounded by less dense radiative and convective zones serving to transport the energy to the surface (the photosphere). The atmospheric layers (the chromosphere and corona) are normally invisible except during a total eclipse. Mass and diameter: 333 000 and 109 times that of earth respectively; mean distance from earth: 149.6 million km (1 astronomical unit) related adjective solar

Often Sun. A medium-sized, main-sequence star located in a spiral arm of the Milky Way galaxy, orbited by all of the planets and other bodies in our solar system and supplying the heat and light that sustain life on Earth. Its diameter is approximately 1.4 million km (868,000 mi), and its mass, about 330,000 times that of Earth, comprises more than 99 percent of the matter in the solar system. It has a temperature of some 16 million degrees C (27 million degrees F) at its core, where nuclear fusion produces tremendous amounts of energy, mainly through the series of reactions known as the proton-proton chain. The energy generated in the core radiates through a radiation zone to an opaque convection zone, where it rises to the surface through convection currents of the Sun’s plasma. The Sun’s surface temperature (at its photosphere) is approximately 6,200 degrees C (11,200 degrees F). Turbulent surface phenomena analogous to the Earth’s weather are prevalent, including magnetic storms, sunspots, and solar flares. The Sun was formed along with the rest of the solar system about 4.5 billion years ago and is expected to run out of its current hydrogen fuel in another 5 billion years, at which point it will develop into a red giant and ultimately into a white dwarf. See Table at solar system. See Note at dwarf star.
The star around which the Earth revolves.
Note: The sun is about 4.5 billion years old and is expected to remain in its present state for approximately another six billion years; it will eventually evolve into a white dwarf.
(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).
