Author's note: I was one day wondering when Halley's comet will return so I decided to write about comets.
When you look up at the sky on a clear night what do you see? Stars and the occasional comet. I wonder how they get that streak behind them and how they move through space. I think they are very interesting things because they are constantly moving and they never stop.
Comets are made up of Space Dust and Ice which is weird because if an astronaut took off a helmet in space his blood would boil not freeze. Then the center (or Nucleolus) of the comet releases gases that trail off behind it. And to move they have to use the gravity of other planets and stars to slingshot around and launch back.
Halley's comet is a famous comet causing bad things to happen. Like in 1066 when the comet passed the Norman took over England. Some other things also happened when the comet passed at different times.
Comets are very strange. I really like how comets can keep going forever. In the future I hope to see Halley's comet. It only comes every 76 years and it will next come in 2061.
