The Cosmic Snowballs: Comets
Did you know there are cosmic snowballs traveling through space? These are called comets! Comets look like a bright star with a tail. They come from far away, from places called the Oort Cloud and the Kuiper Belt. These cosmic snowballs are made of rock, dust, and ices. They have three parts: a nucleus or the heart, a coma or the cloud around the heart, and a tail that always points away from the sun. One famous comet is Halley's Comet. It comes near Earth about every 76 years. Scientists study comets like Halley's to learn more about our vast universe. Next time you see a comet, remember, it's a cosmic snowball on a journey!
