A classical Kuiper belt object, also called a cubewano (/ˌkjuːbiːˈwʌnoʊ/ "QB1-o"),[lower-alpha 1] is a low-eccentricity Kuiper belt object (KBO) that orbits beyond Neptune and is not controlled by an orbital resonance with Neptune. Cubewanos have orbits with semi-major axes in the 40–50 AU range and, unlike Pluto, do not cross Neptune's orbit. That is, they have low-eccentricity and sometimes low-inclination orbits like the classical planets.
The name "cubewano" derives from the first trans-Neptunian object (TNO) found after Pluto and Charon: 15760 Albion, which until January 2018 had only the provisional designation (15760) 1992 QB1.[2] Similar objects found later were often called "QB1-o's", or "cubewanos", after this object, though the term "classical" is much more frequently used in the scientific literature.
Objects identified as cubewanos include:
- 15760 Albion[3] (aka 1992 QB1 and gave rise to term 'Cubewano')
- 136472 Makemake, the largest known cubewano[citation needed] and a dwarf planet[3]
- 50000 Quaoar and 20000 Varuna, each considered the largest TNO at the time of discovery[3]
- 19521 Chaos, 58534 Logos, 53311 Deucalion, 66652 Borasisi, 88611 Teharonhiawako

- 486958 Arrokoth
136108 Haumea was provisionally listed as a cubewano by the Minor Planet Center in 2006,[4] but was later found to be in a resonant orbit.[3]
