{{mpl|2014 OE|394}} is a large [[Astronomy:Classical Kuiper belt object|cubewano]] in the [[Astronomy:Kuiper belt|Kuiper belt]] that was discovered in July 2014 by the [[Astronomy:Pan-STARRS|Pan-STARRS]]-1 telescope, and announced on 17 July 2016.<ref name="MPCannounce">{{cite web|title=MPEC 2016-O95 : 2014 OE394|url=http://www.minorplanetcenter.net/mpec/K16/K16O95.html|website=Minor Planet Center|publisher=International Astronomical Union|accessdate=24 July 2016}}</ref> 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.<ref name="JPLorb"/> Mike Brown's website lists it as a "possible" dwarf planet, with an estimated diameter of 337 kilometers.<ref name="MikeBrownEstimate">{{cite web|last1=Brown|first1=Mike|title=How many dwarf planets are there in the outer solar system? (updates daily)|url=http://web.gps.caltech.edu/~mbrown/dps.html|website=Mike Brown's Planets|accessdate=24 July 2016}}</ref>

{{mp|2014 OE|394}} is also somewhat close to the ''[[Astronomy:New Horizons|New Horizons]]'' probe, about 8.7 AU away on 1 January 2017, and 7.5 AU on 1 January 2019. Considering its large size, it would make a possible imaging target, as [[Astronomy:15810 Arawn|15810 Arawn]] was in early 2016. However, as {{mp|2014 OE|394}} is currently over 10 times further than the other was, it would have much lower-precision data.
