Why asteroids burn up while entering the atmosphere?


     Asteroids are rock-solid objects that randomly moves here and there in space. The size of these asteroids varies from a tennis ball to a small planet. Most of the asteroids in our solar system revolve around the sun in an elliptical path between Mars and Jupiter. Approximately more than 50,000 asteroids move in there with varies in mass.


What are the different types of space rocks?

There are more types of celestial objects around the solar system:


  • Asteroids


  • Meteoroids


  • Meteorites


  • Comet


  • Planets


  • Dwarf Planets


  • Natural Satellites

Why do they burn?


     When asteroids enter the Earth’s atmosphere. This atmosphere consists of a large amount of air. Asteroids move into this atmosphere with the velocity of thousands of km per hour. When it hits the atmosphere, the air in front of it compresses rapidly. That increase the temperature to rise to very hot. From this, these asteroids burns.


     Most of the asteroids completely burnt themselves by the atmosphere friction and the velocity of the asteroid. But, a few of them still remain some mass and bang into the earth surface. When a small piece of asteroid hits the earth surface, we call it a meteoroid.


Why not skydivers?

     Skydivers jump to the Earth inside the atmosphere. Also, they jump at zero velocity(free-falling object). Because of the minimum speed, they cannot burn. For example, a 100 kg person jumps from 4000 meters, then he needs to spend 1000 kcal/kg. Which is equivalent to burn 100kg of water with a 10 degree Celcius. So, this amount of energy not enough to burn the skydiver.

  1. Hi Admin! The content you shared here about Asteroids is very interesting. Kids find it very interesting to study the Universe. Primary science teachers play a crucial role to develop an interest in the kids for the science subjects and prepare a good foundation for their higher classes. Interesting and fun science experiments are very helpful to teach kids in an effective manner. I came across an interesting article in which some Physics games to teach forces to the kids are discussed. If teachers teach with the help of various games, real-world examples, and quizzes then kids will find studying science more interesting. Thanks for sharing!
