(590218) 2011 UD63, chemical scattering and disintegration

(590218) 2011 UD63 is a centaur discovered in October of 2011. There are prediscovery images back to September of 2011, December of 2008, October of 2008 and October of 2000.

It reached the perihelion in May of 1970 (also in November of 1904). It reached the aphelion in March of 2003 (also in August of 1937).

Like 1994 TA, it is part of the group of centaurs with orbits located between the zone of orbital piercing form Saturn towards Uranus and the zone of orbital piercig from Uranus towards Neptune. It has a perihelion of 11.06 AU and an aphelion of 21.44 AU. The semimajor axis is at 16.25 AU. It has an orbital period of 65 years and 203 days. It has an inclination of  10.7º. It has a diameter of about 74 km.


Orbital resonance:
9:20 with Saturn (99.9)
9:7 with Uranus (99.7
)



Greek Mythology

Pylenor was the centaur that having been wounded by Heracles’ poisoned arrows (which were soaked with Hydra’s poisoned blood), washed himself in the river Anigrus, thus providing the river with a peculiar odor.

The centaur 2011 UD63 combines the opening quality of the zone of orbital piercing from Saturn toward Uranus, with the intangible quality of the zone of orbital piercing from Uranus toward Neptune, in which there are many scattered elements and their identity is not clear or there is confusion about the connections between these.

The centaur 2011 UD63 is related with processes of disintegration and scattering of organic or inorganic elements and compounds, which in general are difficult to perceive with the naked eye or through the sense of smell.

Sometimes, a ray of light through a window makes visible the dust in suspension, but most of the times, the form of detection is indirect.

Marie Curie, pioneer in radioactivity studies, has 2011 UD63 in Pisces in conjunction with Bienor, which are in quintile with the Crossing Point of Age Progression in the Signs Horoscope.
