Comets Thesis Statement

My Thesis statement is that Comets may or may not support life it self but we can infer that comets brought water and rock adding to form planets when crashing.Comets are made up of a portion of small planets so they could may be the recipe for making planets.Comets have highly eccentric orbits which take them far beyond the orbits of pluto.What comets are made of are so what called “dirty ball or dirty snowball”.Did you know that because of the dirty snowballs the comets tails melts.It melts because it passes by the sun’s orbital path.If your wondering why there called “dirty snowball” because they are made up of organic compounds like Ice,rock,and other kinds of compounds.The comets closest point of the sun is called “perhelion’’ and distants
points away is called “aphelion”.Perihelion means “the point in the path of a planet nearest to the sun.”Aphelion is comparing perihelion which means the opposite”the point in the path of a planet farthest away from the sun.
