25 Most Impressive Comets Ever Seen

Have you ever had the privilege of witnessing a comet? These brilliant astronomical objects have been the source of many superstitions and tales. But comets are not the source of enchantments or anything of the sort. Rather comets are considered to be the left overs from the formation of stars and planets billions of years ago. They are made of different types of ice, such as water, carbon dioxide, ammonia, and methane, mixed with dust with an icy center—known as a nucleus—surrounded by a large cloud of gas and dust often called the coma. This is the formula for all of the most impressive comets.

A comet’s path and motion is dictated by gravity from the planets and stars they pass. Therefore when a comet is in our solar system, most of the gravity affecting its motion is due to the sun and as it gets closer to the sun the faster it moves (because the closer an object is to the sun the stronger the sun’s gravity is on it). As well as moving faster, a comet’s tail grows because more of its ice evaporates. As of early 2016, there are more than 5,260 known comets, a number that is steadily increasing. However, only a few have made a huge impact on our skies. Are you ready to learn about these fascinating comets? Then check out these 25 Most Impressive Comets Ever Seen.
