Examples of galaxies are the Milky Way galaxy, the Andromeda galaxy and many more. Galaxies are group of stars planets and other heavenly bodies that are grouped and clustered together. They scattered all over in the Universe.

The Solar System in where our planet Earth as well as the other planets belongs is located in one of these Galaxies; this is called as the Milky Way.

There are many stars that scattered in the entire universe. One of these stars is our very own Sun. The Sun is a star and this is the nearest star to the planet Earth.

The sun is the biggest body in the Solar System. It is a star, the nearest star in the planet earth. The astronomers believed that the sun was formed about 5 billion years ago. The sun is considered as the center of the Solar System.

The orbital paths of the planet as well as the other members of Sun’s family are controlled by the strong gravitational force of the Sun. The Sun’s surface has a strong gravity; it is about 28 more times greater than of the Earth’s gravitational force.

The sun also rotates on its own axis. At its equatorial region, it rotates in every 27.28 earth days. At its polar region, it rotates in every 34 earth days.

The distance of the Sun from the Earth is about 149 million kilometers and its light reaches the Earth in about 8 minutes. The diameter of the sun is about 109 times bigger than the diameter of our planet and its weight is about 330,000 times heavier than the planet Earth. The Sun is composed mostly of 24.85 % helium, 0.77 % oxygen, 0.29% carbon, 73.46% hydrogen, 0.16 % iron, 0.12 % neon, 0.09 % nitrogen, 0.07 % silicon, 0.05 % magnesium and 0.04 % sulfur.

The temperature of the surface of the Sun reaches about 6,000 K; this rises to about 15 million K at the Sun’s center.

The sun provides the Earth with the energy that all the living things need in order to survive. The heat coming from the sun is absorbed by the plants. This energy is transformed and absorbed by the other living organism including the humans.
