C/2017 K2 is a long-period comet discovered in May 2017 by astronomers using the Pan-STARRS1 telescope in Hawaii. It is notable for its large size and bright nucleus, which is estimated to be about 18 kilometers wide. The comet is believed to originate from the Oort Cloud, a distant region of our solar system filled with icy bodies. As it approaches the Sun, C/2017 K2 is expected to become visible to the naked eye in mid-2022. Its orbit takes it on a journey that spans thousands of years, making it a fascinating object for both amateur and professional astronomers studying the dynamics of comets and their behavior as they near the Sun.
