SUN-THE ULTIMATE SOURCE

Sun , the ultimate source of energy is unique in every aspect to every material in this solar system.It is one of the intelligently glowing star in our Universe.It does not has a surface at all as we imagine. It is completely made of hot gaseous material.

The internal temperature of sun is about 5500 degrees C (10,000 degrees F). star temperatures are measured in a metric unit called the Kelvin (abbreviated K). One Kelvin equals exactly 1 Celsius degree .

Sun gets its energy from its internal nuclear reactions that is precisely at its core.In its nuclear fusion reaction the two atoms combine and creates a new atom. Fusion produces energy by conversion of nuclear matter into energy.

The period of sun is about a month.Since the sun is a gaseous material rather than a solid one, different places of the sun rotate at different speeds. Equator takes about 25 days to rotate once, whereas gas at higher latitudes take slightly more than 28 days.
