The best comet

Marcus cook

Here it come

Is it a bird, is it a plane, no it a comet. Which out will it hit earth. I wonder what make comets,what happen out side of the earth,and are there more people out side of the earth. While everyone was in school we put a big camera on a comet now we can see every thing that is out of the earth. Comet are made up of leftovers from the gas, dust, ice and rocks that initially formed the solar system about 4.6 billion years ago. But I really wonder will the comet hit earth.
