    (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. [2] 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. [1] 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]

    (208996) 2003 AZ84 is a trans-Neptunian object with a possible moon located in the outer regions of the Solar System. It is approximately 940 kilometers across its longest axis, as it has an elongated shape.
