Charon came into existence. It is unlikely to be relatively recent debris originated in collisions within Pluto's system or a captured object. Observation Arawn is currently relatively close to Pluto. In 2017 it was only 2.7 AU from Pluto. Before 486958 Arrokoth was discovered in 2014, Arawn was the best known target for a flyby by the New Horizons spacecraft after its Pluto flyby in 2015. Arawn was one of the first objects targeted for distant observations by New Horizons, which were taken on 2 November 2015. More observations were made in April 2016. On 2 November 2015 Arawn was imaged by the LORRI instrument aboard New Horizons, making it the closest observation of a Kuiper belt object other than the Pluto–Charon system by a factor of 15. Between 7–8 April 2016, New Horizons imaged Arawn from a new record distance of about 111 million kilometres, using the LORRI instrument. The new images allowed the science team at Southwest Research Institute (SwRI) in Boulder, Colorado, to further pinpoint the location of Arawn to within 1000 kilometers. The new data also made it possible for scientists to observe its rotation period, which was determined to be 5.47 hours. Arawn occulted a star on 25 August 2022.
