It will come to perihelion in January 2016.
Assuming a generic TNO albedo of 0.09, it is about 146 km in diameter.
Simulations by Emel’yanenko and Kiseleva in 2007 show that (131696) 2001 XT254 is librating in a 3:7 resonance with Neptune. This libration can be stable for less than 100 million to billions of years.
It has been observed 22 times over 4 oppositions.
