The Asteroid that Once Wiped out the Dinosaurs

By Khrishnav Parasuraman


A comet 5 kilometers wide is heading past earth. But it will not hit earth. About 65 million years ago an asteroid this big knocked out the dinosaurs.  


This comet was first spotted in March by Neowise.  Neowise is  Nasa Mission. Their goal is to spot asteroids or comets that may wipe out life on earth.

One big problem about comets is that they are made of ice. So they might melt when they approach that sun. Luckily that didn’t happen to comet NEOWISE since it is big.

This comet was visible to the naked eye but only in the evening. But this week people will be able to see it at other times.
