Do you know how big the sky really is? How many great scholars, astronomers have spent years trying to measure its size. How many kinds of the accounts have been calculated. But where is the border? Space research has been going on for ages. Incredible how much has been written about that space. Out of our sight, this distant sky is space. And if this space is compared to the sea, then our earth will be a drop of water in its chest. And the hundreds of billions of people that live on the face of the earth seem to be tiny germs. The special thing that catches our eye in the distant sky is the sun. It is so bright during the day that it cannot be looked at well. In the morning or evening it becomes like a reddish. Do you know how big this sun is from the earth? Listen guys, if 13 million earths are brought together then it will be equal to the sun! It looks so small because the sun is so far away. The distance of the sun from the earth is 93 million miles. As a kilometer, it is 14 crore 96 lakh 30 thousand kilometers. And with this sun in the middle, our earth revolves around it. Not just the Earth, but many other celestial bodies like the Earth are orbiting the Sun. We call them planets.
The vast expanse of space beyond the solar system is littered with countless points of light that we call stars. With the naked eye we can see three thousand stars from one hemisphere of the earth. But if you look through binoculars, the amount is many times more. Scientists have found hundreds of billions of stars. But the amount is more. According to scientists, these are larger in size than the Sun. Maybe several times! Scientists have come up with a star called 'Mira', which can be filled with three thousand nine hundred billion Earths like ours!
There is a cluster of stars called Hercules, which is measured from one corner to the other by multiplying 3600 by 56060000. Many people are dizzy! But this is true. You all know that the highest place in the world is Mount Everest. 5 miles from land or sea level. And the sun is 93 million miles away. Many of you do not know that we do not see the sun when it appears in the sky of the earth. See you after 7 minutes! That means it takes eight minutes for sunlight to reach the earth. The speed of light is 1 lakh 6 thousand miles per second.
You can tell how long it will take for light to come to Earth from the nearest star we see. Four years and three months! Now calculate how long it would take for the distant stars to get the light if the light condition of the nearest star was like this. Every night we look up at the sky and see how bright they are. The stars we see at night are not the stars of that time, they departed one day long ago. Then he came running and appeared before our eyes. On the day that light left, there may not have been any human beings on earth. Maybe a giant animal would roam the world. Not only planets but also how many more bright astronomical stars orbit. Many have heard the name of the nebula. The nebula is actually a burning object. They rule over billions of miles of space. One wonders how big a nebula can be. The farthest thing in space is the nebula. From which it will take 500 million years for light to come to the earth! Just as the earth is the inhabitant of space, so are eight other planets orbiting the sun like the earth. The closest planets to the Sun are Mercury, then Venus, Earth, Mars, Jupiter, Saturn , Uranus, Neptune and Pluto.
In space, the kingdom of the sun, the kingdom of the planets is beyond the kingdom of the stars. The stars are much larger than the planets. We can't tell the difference because the planets and the stars look the same to us. In fact, our solar system is made up of innumerable constellations, planets, planets and the sun. And the creation of all this is from that nebula. There are also meteors, comets. How many more inhabitants of space. Many of which remain unknown.
