2006 HH123, also written as 2006 HH123, was a lost object with an assumed eccentricity. If it had been a scattered-disc object it would have had an absolute magnitude of 5.2, and been a possible dwarf planet. The preliminary orbital elements (as displayed in the infobox to the right) were calculated using only three observations over a period of one day, hence its orbit was very poorly known and it quickly became lost.
Of the three discovery images, the first one is an unidentified object, the second one was identified as main-belt asteroid 130902, and the third image shows nothing at the measured position. The three observations of 2006 HH123 were deleted on 6 November 2014, and the provisional designation 2006 HH123 is no longer listed in the Minor Planet Center database.
