2006 HH123, also written as 2006 HH123, is a lost scattered-disc object. With an absolute magnitude of 5.2[2], it is a dwarf-planet candidate. The preliminary orbital elements as displayed in the infobox are calculated using only three observations over a period of one day[1][2][3], hence its orbit is very poorly known and it is considered lost.
