(316179) 2010 EN65, changes that seemed impossible

(316179) 2010 EN65 is a centaur discovered in March of 2010. It has a perihelion of 21.0 AU and an aphelion of 40.3 AU (2007 RW10 family). It has an inclination of 19.2º. It has a diameter of 183 km. There are prediscovery images back to January of 2006, February of 2005, January of 2003, February and January of 2002, November and March of 1997, December of 1992, January of 1990 and November of 1989. 

When things have been running in a fixed direction for a long time, seems very hard to stop or revert that tendency. (316179) 2010 EN65 has the ability to change fixed tendencies or static situations in a amazing way. What becomes impressive is the magnitude of the system that is being transformed, like in the movie "Unstoppable" (2010), "Buried" (2010), "Prince of Persia: Sands of Time" (2010), "Inception" (2010), "Stone" (2010)
, "Fair Game" (2010), "The Next Three Days" (2010) and "Luftslottet som sprängdes (The Girl Who Kicked the Hornet's Nest)" (2010).

Like all transformations of chaotic attractors (plutinos, scattered disc objects, centaurs, as well as the Sun and Venus), they took a long time of unnoticed changes, before the rapid and strong changes start

Differences between (309239) 2007 RW10 and (316179) 2010 EN65 

Both are highly chaotics with orbits between Uranus and the Kuiper belt, but while (309239) 2007 RW10 is related to a high Lyapunov exponent [the speed at which the system changes between different phase states], (316179) 2010 EN65 is related to a high fractal dimension [the size or magnitude of the system that is changing between different phase states].
