primary body nor its satellite have been named.[2]

Orbit and classification

2000 YW134 orbits the Sun at a distance of 41.0–73.8 

came to perihelion in 1979,[12] and is currently at about 46.5 AU from the Sun, with an apparent magnitude of 21.54.[11] It will reach aphelion in December 2197.[12]

2000 YW134 is a

perihelion distance of 38.2 AU – have since secured its 3:8 orbital resonance with Neptune.[6][14]

Numbering and naming

This

M.P.C. 51853).[15] As of 2021, it has not been named.[2] According to the established naming conventions, it will be given a mythological name associated with the underworld.[16]

Physical characteristics

The surface of 2000 YW134 is moderately red in the visible part of the spectrum. Its

color indices have also been measured several times, giving an averaged value of close to 1.0 and 0.5, respectively, for a combined B−R magnitude of 1.50.[9]

Diameter and albedo

In 2010, observations with the Herschel Space Observatory constrained the object's geometric albedo to no darker than 8%, and allowed to place an upper limit to its effective mean-diameter of 500 km (310 mi), as no thermal radiation had been detected.[8] However, according to Michael Mommert's dissertation in 2013, the object has a much higher albedo of 0.408±0.329, which greatly reduces its effective diameter to 229 km (140 mi).[7]

Satellite

On 25 October 2002, observations in the

primary and a diameter of 75 km (47 mi) for the secondary, based on a secondary-to-primary diameter ratio of 0.347, for a difference of 1.3 magnitudes between the two objects. The satellite, designated S/2005 (82075) 1, orbits its primary every 10 days (estimated) at an average distance of 1,900 km (1,200 mi).[7]
