(469372) 2001 QF298

February 16, 2023

(469372) 2001 QF298, provisionally known as 2001 QF298, is a resonant trans-Neptunian object that resides in the Kuiper belt in the outermost region of the Solar System.[6] It was discovered on August 19, 2001 by Marc W. Buie.[1] 2001 QF298 is a plutino, meaning that it is locked in a 3:2 orbital resonance with Neptune, much like Pluto.[6]

Physical characteristics

In 2012, the size of 2001 QF298 was estimated based on thermal radiation data obtained with the Herschel Space Telescope. The result was 408.2+40.2
−44.9 km.[6]

In the visible light, the object appears to have a neutral or slightly red color.[7]

Dwarf planet candidate

When first discovered, 2001 QF298 was calculated to have an absolute magnitude (H) of 4.7.[2] Light-curve-amplitude analysis from 2008 showed only small deviations, which suggested that 2001 QF298 could be a spheroid about 480 kilometres (300 mi) in diameter with small albedo spots and hence a dwarf planet.[8] It is not included in the same authors' list of dwarf-planet candidates from 2010 because, having an absolute magnitude of 5.4 and assumed albedo of 0.1, it would be less than the cut-off size of 450 kilometres (280 mi)[9] (the same criteria as in the first paper).[8]
