(556416) 2014 OE394 is a large cubewano in the Kuiper belt that was discovered in July 2014 by the Pan-STARRS-1 telescope, and announced on 17 July 2016.[5] It is one of the brighter trans-Neptunian objects, being the 34th brightest cubewano as of 23 July 2016. Its exact size is unknown, but is most likely between 240 and 730 kilometers across.[4] Mike Brown's website lists it as a "possible" dwarf planet, with an estimated diameter of 337 kilometers.[2]
2014 OE394 was observed by the New Horizons probe in September 2017 and August 2018. It passed close by:[6] about 8.7 AU away on 1 January 2017, and 7.5 AU on 1 January 2019.
