Asteroids Definition

Asteroids are heavenly bodies that circle around the sun. The word Asteroid implies star-like and is gotten from the Greek words – astor (star) and oid (shape).

The Extinction of Dinosaurs

They are accepted to be remainders of the humungous dust storm and gases that framed the sun and planets more than 4 billion years prior. The vast majority of them lie in a solitary belt between the circles of Mars and Jupiter. Now and again changes in gravitational streams and different powers in space cause them to get removed from their circle and move far from the principle belt. It is trusted that a goliath Asteroid collided with earth a huge number of years prior causing such outrageous changes in climate and the termination of dinosaurs.

How is Asteroid Belt shaped?

Researchers trust that the Asteroids belt in our close planetary system could have shaped in one of two different ways.

  1. There existed a planet among Mars and Jupiter that separated into the belt because of a crash with another heavenly body.
  2. The stone material in the Asteroid belt was not able wire into a planet like the others because of Jupiter’s huge gravitational power.

Asteroids can be anyplace from a couple of feet to a few kilometers in distance across. The biggest Asteroid in the belt is known as Ceres. It is 950 km wide, so expansive that it really has its very own order, called a diminutive person planet.
