What is Asteroids?

Asteroids are the rocky object which orbit the sun, and due to their small size they are not called as Planets. they may also be called as small or minor planets. there are a large number of asteroids present in our solar system in millions. mostly of them are found in the asteroid belt- which is the region between Mars and Jupiter, not only in the asteroid belt these also orbit the planets and some asteroids are having the same path with the planets. which increases the chances of hitting the planets.

As of the large numbers of asteroids present so there are many asteroids which makes a flyby with our planet Earth. some of them are so close too which may cause hazardous for our Earth. Nasa and our scientists are a lot of years ahead of looking for the asteroids as they will hit or make a flyby with our planet. here we provided a lot of information about asteroids and there is a lot left too, we will cover it up in next posts, for regular notification follow us on Instagram and Facebook that you can see in Social Media Plugins and Share this article with your friends.
