Comets 2015 © Scott Stein My Banana is a Pink Umbrella A Comet is a rock in space that is very icy and forms a coma and a tail. Some comets originate from the Kuiper belt.

The Oort Cloud 2015 © Scott Stein My Banana is a Pink Umbrella Most comets come from the Oort Cloud, a region of space far beyond the Kuiper belt, which has billions of comets.

Comets: Coma’s and Tails 2015 © Scott Stein My Banana is a Pink Umbrella A coma is the atmosphere of a comet & the tail is a formation of dust & gas behind it. Coma tail

Comets Tail Formation 2015 © Scott Stein My Banana is a Pink Umbrella A tail forms due to the heat of the Sun evaporating frozen gases and releasing dust. The tail always points away from the Sun because the Sun’s cosmic wind pushes it away.

Comet Tail Formation: 2015 © Scott Stein My Banana is a Pink Umbrella The tail of a comet can only be seen when it gets close enough to the Sun for it to be heated up. Video: What are Comets?What are Comets?
