The sun is the closest star to the earth in the form of a huge-clump of glowing gas and the shape of which is spherical. The sun is the largest object and the center of our solar system. By the attraction of gravitation owned by the sun, celestial bodies such as planets, asteroids, comets, and satellites can still revolve around the sun in their orbits.
The sun is a celestial body that can emit its own light, therefore the sun is called a light source. The sun is grouped into the stars that that can produce and emit their own light. Meanwhile the characteristics of the sun’s condition are as follows:
The sun with very high core temperature produces energy. The emission of the sun energy happens as the effect of the effect of the presence of chemical reaction in the sun’s core. The chemical reaction that happens is fusion reaction, that is union of hydrogen atom neclei forming helium atom nuclei. The chemical reaction causes the mass of the sun to decrease.
The process is as follows
“Each nucleus of hydrogen makes fusion so the helium nucleus is formed, also 2 positrons (particle similar to electron with positive charge), also energy of 24.7 Mev.”
The amount of sun energy that is emitted every minute is as follows.
