- Similar in many languages, “Sun,” related to Latin’s “sol,” was represented in ancient Greece as Helios, god of 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 star at the center of the Solar System. It is a massive, hot ball of plasma, inflated and heated by energy produced by nuclear fusion reactions at its core. Part of this internal energy is emitted from its surface as light, ultraviolet, and infrared radiation, providing most of the energy for life on Earth.
