Comets, Meteors and Asteroids

                                           

Hello everyone, today we are going to talk about Comets, Meteors and Asteroids. Let's first talk about what are Comets. Comets are made up of ice, dust and rock particles and have arts like the Coma, Tail. When a Comet gets close to the sun, it's ice melts and then a mix of gas and dust are pushed away from the comet from solar winds and then that creates a tail called the Coma.

Now let's look at what are Meteors.

Do you know that there is a difference between Meteoroids, Meteors, and Meteorites?  Well, a Meteoroid is a space rock smaller than an Asteroid. If a Meteoroid enters earth's atmosphere, it becomes a Meteor ,and parts of the Meteor that don't burn up become Meteorites. Have you seen a Meteor shower? If you have, you probably don't know why they occur. So let me explain why Meteor shower occurs.Meteor shower occurs, when the earth passes through the dusty orbit of a comet.

The last thing I am going to present to you is, Asteroids; Asteroids are chunks of rock that can usually be found in the Asteroid Belt, between Mars and Jupiter. There are some difference between Asteroids and Comets . Comet has ice in them and  Comets have tails.Comets have more elliptical orbit than  Asteroids.Comets appear more fuzzier than Asteroids.

you may ask Why do we need to study comets ? Well Scientist study Comets to know more about the origin of our Solar System.  Here are some fun facts.

1. Haley's Comet revolves around the once every 76 years

2.Scientists have found more than 90,000 Asteroids in the asteroid Belt

3. Comets are sometimes called a dirty snowball

Hope you enjoyed my blog. Bye now.
