C/2017 K2 (PanSTARRS) is an Oort cloud comet with an inbound hyperbolic orbit, discovered in May 2017 at a distance beyond the orbit of Saturn when it was 16 AU (2.4 billion km) from the Sun. Precovery images from 2013 were located by July.[8] It had been in the constellation of Draco from July 2007 until August 2020. As of June 2022[update], the 3-sigma uncertainty in the current distance of the comet from the Sun is ±5000 km.[9] The comet is record breaking because it is already becoming active at such a distance.
