C/2016 R2 (PanSTARRS) is a comet, discovered using the Pan-STARRS telescopes on September 7, 2016. The comet attracted attention from many astronomers as it approached its closest point to the sun in May 2018. [3] It has been observed to have a very complex tail, which has been suggested to be due to a fast rotation period of the nucleus.
The comet orbits the Sun on a 20,000 year orbit, which takes it out about 740 AU (Sun-Earth distances). [4] It was found to differ from typical comets, and was found to be rich in Carbon monoxide (CO) with a blue coma. [4] The blue color is thought to come from the rich amounts of carbon monoxide being ionized. [5] The comet was also noted to be rich in nitrogen. [6]
The comet was observed by a submillimeter wavelength telescope in the late 2010s. [4]
The comet made its closest approach to the Sun in May 2018, and its blue, teal, and dust tail were noted as an astronomical target. [5] Blue comets are a less common type of comet. [6]
