(691721) 2014 QY441, also written 2014 QY441, is a resonant trans-Neptunian object in the Kuiper belt. It is in a 3:4 mean-motion orbital resonance with the planet Neptune. It was discovered in 21 August 2014 by the Pan-STARRS project at Mauna Kea Observatory in the big island of Hawaii, United States.

Orbit and classification

2014 QY441 orbits the Sun at a distance of 33.9-39.3 AU every 221.8 years (81048.1 days, semi-major axis of 36.6 AU). Its orbit has an orbital eccentricity of 0.074 and an orbital inclination of 10°, with respect to the ecliptic. The body's observation arc begins with its precovery date at Kitt Peak.

2014 QY441 is a trans-Neptunian object and belongs to a snall number of resonant trans-Neptunian objects with semi-major axes of 36.0-37.0 AU. These objects stay in a 3:4 mean-notion orbital resonance with the planet Neptune, that is, for every three orbits the object makes, Neptune makes four. These objects are located in the inner rim of the Kuiper belt, with the plutinos, inner classicals, and other resonances, a large circumstellar disk of mostly non-resonant classical Kuiper belt objects.

Numbering and naming

2014 QY441 was numbered by the Minor Planet Center on 4 April 2024, receiving the number (691721) in the minor planet catalog (M.P.C. ?). As of 2024, it has not been named.

Physical characteristics

Based on a generic magnitude-to-diameter conversion, 2014 QY441 measures approximately 308 kilometers (190 miles) in diameter, for an assumed albedo of 0.8 and an magnitude of 5.7. Michael E. Brown measures a diameter of 316 km with an absolute magnitude of 5.8 and an albedo of 8%. On his website, Michael E. Brown considers 2014 QY441 as a possible dwarf planet, which is the category with the lowest certainity in his 5-class taxonomic system. As of 2024, no physical characteristics has been obtained from photometric observations. The body's color, rotation period, pole, and shape remain unknown.
