Guys, today I have been talking to you about the solar system. Guys, when you look at the sky at sunset, it feels very good. When you keep looking, after some time, innumerable small objects start shining in the sky. You must have noticed that the luminosity of some objects will be different from others. This is the moon. You may have noticed that this pre-day changes in shape; when it is in the form of a full moon, it is called full moon. And when you see it exactly fifteen days after the full moon, it is half; it is called Ambasya.

Meteorites are small lumps of rocks orbiting the Sun. Sometimes these meteorites come close to the Earth and get burnt, and sometimes they come to the Earth. Its speed is such that when it keeps on flowing, the water rises on the surface due to friction with the air, which causes loss of wealth and people.
