(31824) Elatus is a centaur discovered in October of 1999. The orbit is between Jupiter-Saturn and Saturn-Uranus. It has a perihelion of 7.2 AU and an aphelion of 16.3 AU. It has a diameter of about 45 km. There are prediscovery images back to October and September of 1998. It has an inclination of 5.2º.
Heracles' arrow hits Elatus in the arm, but passes right through, and ends up hitting Chiron.
An actual image of this mythology can be Neo avoiding the bullets of agent Smith in the movie "The Matrix" (1999).
(31824) Elatus has an incredible ability to scape from the most difficult situations, like Morfeo-Neo in the movie "The Matrix" (1999). But is more habitual that he flee before things get worst.
Puer aeternus archetype
The Jupiter-Uranus quality is associated to the puer aeternus archetype (Marie Louise Von Franz; Liz Green), were an individual with immense potential always flee before that potential is achieved, like in the movie "Forces of Nature" (1999), or like in the book of Ursula K. Le Guin "A Wizard of Earthsea" (1968) or like Luke in the movie "Star Wars: Episode V - The Empire Strikes Back" (1980) when he interrupt the training with Yoda.
The 'puer' typically leads a provisional life, due to the fear of being caught in a situation from which it might not be possible to escape. He covets independence and freedom, chafes at boundaries and limits, and tends to find any restriction intolerable. (Wikipedia: puer aeternus)
