Its exact size is unknown, but is most likely between 240 and 730 kilometers across.[3] Mike Brown's website lists it as a "possible" dwarf planet, with an estimated diameter of 337 kilometers.[5]{{mp|2014 OE|394}} is also somewhat close to the New Horizons probe, about 8.7 AU away on January 1, 2017, and 7.5 AU on January 1, 2019. Considering its large size, it would make a possible imaging target, as 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. References1. ^{{cite web |author=Marc W. Buie |author-link=Marc W.
