A comet is and Icy body that releases gas or dust. They are often compared to dirty snow balls, though recent research has led some scientist to call them snowy dirt balls. Comets contain dust, ice, carbon dioxide, ammonia, methane and more. Some researchers think comets might have originally brought some of the water and organic molecules to make up life here.

Comets are really cold but when it goes by the sun it burns up something is so hot that you might even burn up. A comet also has two tails. but not every comet is the same they are all different. Comets can be any shape and any size. But comets are really cool. Comets also sometimes orbit the sun that's how they burn up.
Every comet has a nucleus. Between 1 and 10 kilometers (0.6 to 6 miles) in size. The ice is made of varying amounts of water, Carbon Dioxide, Ammonia, and Methane. A planet is a small world that scientist sometimes planetesimals. Comets come from two places the Kuiper belt and the Oort cloud.
you could never live on a comet but if you could I wouldnt
