Today we will know what are meteors and meteorites? (What are Meteors and Meteorites?) And if you understand all the necessary information related to them in full detail, then stay tuned from beginning to end so that we tell you what are meteors and meteorites? If the complete information can be explained in easy language with the image, then let's start and know what are the asteroids before?

Asteroid
Asteroids revolve in the orbit of Mars and Jupiter, they are the broken parts of the planets. But due to the gravity of Mars and Jupiter, they get stuck between these two planets, the asteroids are visible even after the planet Varuna. You can understand through this image. So you must have understood that what is an asteroid? Now we know what is called a meteor?

Sorry Friend: In the image by mistake, Shudra planet has been written instead of asteroid. please planet Asteroid .
Meteor
The asteroid gets pulled due to the gravity of Mars and moves forward on its own. This asteroid enters the Earth's atmosphere. Due to friction in the atmosphere, it starts burning. Which we are also called the falling star or the star on the ground . When these meteors fall on the earth, we call them meteorites . The crater is formed due to meteorites. the crater . Some examples of which:
- Lonar Lake
- Natal of South Africa
- Arizona of USA (largest)
Dinosaurs died due to the fall of a meteorite named Egypta and the Pacific Ocean has been formed there. The meteors that fall in the direction of the Earth's rotation, due to which their speed becomes 72 kilometers per second (72 km/sec) . Now we know what are bolites?

bolite
When a meteor falls against the direction of the Earth's rotation, it is called a bolite . It looks very shiny. Its speed is 12 kilometers per second (12 km/sec) . When it falls to earth, it is called a tectite .
Major Impacts of Meteorites
- When they enter the atmosphere, they become powdered due to rotation, due to which Red Rain occurs.
- When they enter the atmosphere, they start burning due to friction. Due to which the temperature rises and global warming occurs.
- Due to their fall, the mass of the earth increases, due to which the gravity also increases.
- Due to their fall, the speed of rotation of the earth decreases. 900 million years ago the Earth rotated on its axis in 18 hours , that is, the duration of the day was 18 hours . .
- 41000 years ago the Earth was tilted by 21 degrees ( 21° ), which has become 24 degrees ( 24° ) at present. Which we calculate at ( 23½° ).

We know what are the effects of meteorites? we know that called a comet?
Comet
this dust particles and revolve around the Sun. When it gets closer to the Sun, it burns or starts glowing after getting high temperature. Their tail is always in the opposite direction of the Sun.

Taiko Ko was the discoverer of the tail . The cusp also revolves around the Sun, but it does not intersect the orbit of any other planet because their orbit and the orbit of other planets are up and down. The tail star called Seki is visible to us during the day. The tail star named Eki is visible in 3 years. called kahutec is visible in the year 7600. The cusp of Heli is visible at the age of 76. It will be visible on 3 February 2062 , whereas before it was visible on 9 February 1986 .
- Ptolemy said that the Sun revolves around the Earth.
- Copernicus discovered the solar system and said that the Earth and other planets revolve around the Sun.
- Kepler gave the theory of planetary motion and said that the planets move in ellipses and their speed increases as they get closer to the Sun.

- Galileo proved this theory by making a visionary.
- We get to know about the expansion of the universe through the Hubble telescope.
Conclusion,
Many thanks for giving your valuable time
