"A star is a massive, luminous ball of plasma. Stars group together to form galaxies, and they dominate the visible universe. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth, including daylight. Other stars are visible in the night sky, when they are not outshone by the Sun. A star shines because nuclear fusion in its core releases energy which traverses the star's interior and then radiates into outer space. Almost all elements heavier than hydrogen and helium were created inside the cores of stars." Source: http://en.wikipedia.org/wiki/Star

A star is defined as a spherical object with a high density core and a low density gas envelop surrounding this core. Fusion reactions occur in or near this core and this is what makes Sun so bright and hot.
