Measuring about 108–167 kilometres in diameter, it was discovered in 1992 by David C. Jewitt and Jane X. Luu at the Mauna Kea Observatory, Hawaii.

It has received the number 15760[5] and remained unnamed until January 2018 (it was normally referred to simply as "QB1", even though this was technically ambiguous without the year of discovery).

Over one thousand bodies were found in the Kuiper belt orbiting between about 30 and 50 AU from the Sun in the twenty years after finding 15760 Albion.

[18] Based on a generic magnitude-to-diameter conversion, Albion measures approximately 167 kilometers (107 miles) in diameter, for an assumed albedo of 0.9 and an magnitude of 7.0.

According to Mike Brown, who estimates a mean diameter of 108 km (66 mi), the object is too small for being considered a dwarf planet candidate ("probably not").
