2015 KG163, also known as o5m52, is a

perihelion around August 2022[7][a]
at a velocity of 6.5 km/s with respect to the Sun.

It is one a small number of detached objects with perihelion distances of 30 

argument of perihelion is similar to that of 2013 FT28
, but its semi-major axis is larger, such that its orbit may cross that of Planet Nine.
