In 2013, the discovery paper was published.{{r|Mace2013}} DistanceTrigonometric parallax of WISE J004945.61+215120.0 is not yet measured. Therefore, there are only distance estimates of this object, obtained by indirect — spectrofotometric — means (see table). WISE J004945.61+215120.0 distance estimates
