(15760) 1992 QB₁ was the first trans-Neptunian object discovered, in 1992. It is a cubewano, an object in the main Kuiper Belt. (The name "cubewano" derives from "Q B one".)

It 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, but as there is already another asteroid with that name (1613 Smiley ) the name couldn't be used. The asteroid has received the asteroid number 15760, and remains unnamed.
