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.
