"" (also written "(15760) 1992 QB1") was the first trans-Neptunian object to be discovered after Pluto and Charon (moon)Charon. It was discovered in 1992 and is now classified as a cubewano, an object in the main Kuiper Belt. The term 'cubewano' derives from 'QB1'.

was discovered by David C. Jewitt and Jane X. Luu at the Mauna Kea Observatory, Hawaii. The discoverers suggested the name 'Smiley' for the object, (Science@NASA, 13 September 2001) but as there is already an asteroid named 1613 Smiley (named after an American astronomer) the name could not be used. The asteroid has received the number 15760, and remains unnamed; it is normally referred to simply as 'QB1' (this is ambiguous, as it could refer to any of seven other numbered asteroids —, , , , , , and — and many unnumbered ones).

The next three official cubewanos are , , and .
