SUN

The SUN is a massive ball of exploding gas. The sun applies a huge pull towards the earth called the gravitational force. Due to the gravitational force, the planets, moons and other objects, orbits the SUN with a certain speed.

The size of the sun is approximately 587228075236.26 cubic miles with a diameter of 864,906 miles (1,392.500 km) and it weighs 333,000 times as much as the earth. It is made of atoms of hydrogen, helium and self-luminous gases. The reaction between these gases may cause nuclear fusion reaction, given out massive amounts of energy.

The structure of the Sun

The sun’s core is 27 times wider than the earth and has a temperature of about 10,000 ºF (5,600 ºC). The radiative zone surrounds the core. Heat produced in the core spreads through the inner path waves. The convective zone carries the sun’s energy up to the surface.

ECLIPSES

Total Solar Eclipse

The moon occasionally passes between the Earth and the Sun, blocking its light. This is called a total solar eclipse. The Moon can cover the Sun when viewing it from the earth due to a shorter distance compare to that from the moon to the sun. If you close one eye and hold up a coin between your face and a ceiling light, you can see how this works.

During a total solar eclipse, a thin layer of gases around the Sun, called the corona can be seen.

So often, some may consider the SUN a planet but it’s not since it is a massive ball consisting of gas. This object illuminates the EARTH with light depending on the Solaris and eclipses of the MOON.
