(15760) 1992 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 [1], but as there is already an asteroid named 1613 Smiley (named after an American astronomer) the name couldn't 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 five other numbered asteroids —(5322) 1986 QB1, (7026) 1993 QB1, (31114) 1997 QB1, (36447) 2000 QB1, and (52468) 1995 QB1— and a great number of unnumbered ones).
