Comets are fascinating to study because they have rocks and ice left over from the formation of our solar system. As a comet gets closer to the sun, they begin to melt and shed some of their materials forming a long tail. This tail points away from the sun showing that the solar winds are real. With scientific instruments on the ground and in space, scientists can learn much about the materials that helped form our solar system.
