(15760) Albion (provisional name 1992 QB 1 ) is the first Trans-Neptunian object to be found after Pluto and Charon . It was discovered by David C. Jewitt and Jane Luu on August 30, 1992 at the Mauna Kea Observatory in Hawaii . The planetoid is considered the prototype of the “ Cubewanos ”, the “classic” objects of the Kuiper belt with little eccentricity and inclination. The name Cubewano is derived from the provisional name 1992 QB 1 ("QB one").

The discoverers suggested a name for the object Smiley after the figure George Smiley , which, however, had already been assigned to the asteroid (1613) Smiley . 1992 QB 1 was given the minor planet number 15760 and at the end of January 2018 the name " Albion " (after a mythical figure by William Blake ).

Since its discovery, the asteroid has been observed through various telescopes. In January 2018, there were 86 observations over a period of 21 years from 10 oppositions.

Albion was in perihelion at the time of its discovery and is currently moving away from the Sun again. In January 2018 it was 41.3  AU from the Sun.
