2006 HH123
, also written as 2006 HH123, was a misidentified nonexistent object that had a short 1 day observation arc. It was formerly thought to be a lost object with an assumed eccentricity of 0.46. 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 the main-belt asteroid , and the third image shows nothing at the measured position. The three observations of  were deleted on 6 November 2014, and the provisional designation  is no longer listed in the Minor Planet Center database. See also
