2001 QF298, also written as 2001 QF298, is a trans-Neptunian object that resides in the Kuiper belt. It was discovered on August 19, 2001 by Marc W. Buie. 2001 QF298 is a plutino, meaning that it is locked in a 3:2 orbital resonance with Neptune much like Pluto.

Physical characteristics

In 2012 the size of QF298 was estimated based on the thermal radiation data obtained with Herschel Space Telescope. The result is 408.2
−44.9 km.

In the visible light the object appears to have a neutral or slightly red color.
