What is Universe?

The vast empty space around us that consists of stars, solar system, galaxies etc is called Universe.
The major components of the universe are discussed below:

1.Solar system- Basically the name solar system is describing the sun’s family. The sun occupies the centered place. Around the sun the remaining nine planets revolve around in different orbits. Due to the change in rotation of the planets their distances vary with respect to the sun. Rotation also affects the velocity of the planets. As the planets came near to the sun their rotation speed goes on increasing. The motion of all the planets is controlled by the sun’s gravitational pull.

There are nine planets in our solar system. Ordered list of all these planets is given below:
1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune
9. Pluto

The nearest planet to the sun is mercury and the farthest planet is Pluto. So the above list of planets is arranged according to the increasing distances of the planets from sun.

If you will think that this will be difficult for you to recall the list of planets in the same order then there is a simple formula. Cram the line given below:
“My Very Educated Mother Just Served Us Nine Pizzas”. The first character of each word will recall you the name of the planet.

Lots of other heavenly bodies are present in the universe which usually revolves around the planets of the solar system. These heavenly bodies are known as satellites. Moon is also a satellite. It is the natural satellite of earth. Meteors, Asteroids and comets are also part of the solar system.

2. Galaxies: Galaxies are formed by group of starts, gases, and dust particles all are together by strong gravitational forces. Milky Way is one of the galaxies of the universe in which we live. It is also called Akashganga. It appears like an unclear white strip of light elongated across the sky. It is mostly visible on a clear night. Lots of stars including sun (sun is the brightest star) are a part of this galaxy. A Milky Way galaxy contains billions of stars, near about -1011. Like Milky Way lots of other galaxies exist in the Universe. The galaxy count is approximately 1011.

3. Stars: Stars are glowing heavenly bodies. Stars emit light due to their high temperatures. Stars can be seen on a clear night. The nearest star to us the sun. It is the brightest star. On a clear night at a single time the no of stars we can see is near about 2500. The second brightest star is Alpha Centauri. The approximate distance of the star Alpha Centauri from earth is near about 4.3 light years.
