Its exact size is unknown, but it is most likely between 304 and 486 kilometers across. 2014 OE 394 was observed by the New Horizons probe in September 2017 and August 2018. It passed etal Anne J.

Physical Characteristics Size 2014 OE 394 has an assumed diameter of 304 – 486 km, calculated by its assumed geometric albedo of 0.15 +0.08 -0.06, and the authors have acknowledged that it is a possible dwarf planet. Spectra and surface 2014 OE 394 has assumed color indices of B-V 0.996 ± 0.140, and V-R 0.630 ± 0.086, and as said before, its assumed geometric albedo is 0.15 +0.08 -0.06, its assumed bond albedo is 0.054 +0.040 -0.026, and its surface composition is unknown.
