(15760) 1992 QB1 was the first trans-Neptunian object to be discovered after Pluto and Charon. It was discovered in 1992 by David C. Jewitt and Jane X. Luu at the Mauna Kea Observatory, Hawaii. It is a classical Kuiper belt object and gave rise to the name cubewano for this kind of object, after the "QB1" portion of its designation.[7] Decoding its provisional designation, "QB1" reveals that it was the 27th object found in the second half of August of that year.[1] Over 1,500 further objects have been found beyond Neptune, a good number of which are classical Kuiper belt objects.
The discoverers suggested the name "Smiley" for (15760) 1992 QB1,[8] but the name was already used for an asteroid 1613 Smiley, named after the American astronomer Charles Hugh Smiley. It has received the number 15760[2] and remains unnamed; it is normally referred to simply as "QB1", even though this is technically ambiguous without the year of discovery.
Notes
^ Asteroid provisional designations follow a format, in which the year it was discovered comes first, followed by the half-month it was discovered alphabetically (e.g. A=January 1–15, B=January 16–31 and so on,) and then the order of its discovery alphabetically (skipping the letter I) followed by a number (e.g. 1992 QA, 1992 QB, 1992 QC ... 1992 QY, 1992 QZ, 1992 QA1, 1992 QB1 and so on.) According to this, Q=August 16–31 and B1=25+2=27.
