If you've ever wondered what the universe is, the universe is the huge empty space that surrounds us, consisting of stars, solar system, galaxies, etc.
The main components of the universe are discussed below:
1. Solar System: Basically, the solar system is the name that describes the sun family. The sun occupies the center. Around the sun the remaining nine planets revolve around in different orbits. Due to the change in the rotation of the planets their distances vary with respect to the sun. Rotation also affects the speed of planets. As the planets approach the sun their rotational speed increases. The movement of the planets is controlled by the gravitational pull of the sun.
There are nine planets in our solar system. The ranked list of all these planets is as follows:
1. Mercury
2. Venus
3. Land
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune
9. Pluto
The planet closest 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 the sun.
There are many other celestial bodies that are present in what is the universe that usually revolves around the planets of the solar system. These celestial bodies are known as satellites. The moon is also a satellite. It is the natural satellite of the earth. Meteors, asteroids and comets are also part of the solar system.
2. Galaxies: Galaxies formed by the group of starters, gases and dust particles are all joined by strong gravitational forces. The Milky Way is one of the galaxies in the universe in which we live. It is also called Akashganga. It is presented as a clear strip of white light elongated across the sky. It is mostly visible on a clear night. Lots of stars like the sun (sun is the brightest star) are part of this galaxy. The Milky Way contains billions of stars, about -1,011. Like many Milky Way from other galaxies exist in the Universe. The galaxy count is about 1011.
3. Stars: Stars are bright celestial bodies in what is the universe. Stars emit light due to their high temperatures. The stars can be seen on a clear night. The star closest to us the sun. It is the brightest star. On a clear night at once the number of stars we can see is about 2500. The second brightest star is Alpha Centauri. The approximate distance of the star Alpha Centauri from Earth is about 4.3 light-years.
