C/2016 R2 is a long-period comet that was discovered on September 7, 2016. It is part of the Oort Cloud, a distant region of our solar system that contains many icy bodies. This comet has an elongated orbit that takes it far from the Sun, making it a rare visitor to the inner solar system. The comet is notable for its bright appearance and was observed using various telescopes, including the Hubble Space Telescope. As it approached the Sun, it exhibited a coma and tail, which are characteristic features of comets as they heat up and release gas and dust.
