Kozai resonance

2004 XR190 y (145452) 2005 RN43 have unusual orbits because, in spite of its low excentrity (almost circular orbits), they have high inclination over the ecliptic plane. 

In celestial mechanics, the Kozai mechanism, or the Lidov–Kozai mechanism, causes a periodic exchange between the inclination and eccentricity of an orbit. The effect was described in 1961 by the Soviet specialist in space dynamics Michael Lidov while analysing the orbits of artificial and natural satellites of planets, and in 1962 by the Japanese astronomer Yoshihide Kozai while analyzing the orbits of the asteroids. Since then this effect has been found to be an important factor shaping the orbits of irregular satellites of the planets, trans-Neptunian objects, and a few extrasolar planets and multiple star systems.

Orbits with high inclination, getting into the unknown

Orbits with high inclintion over the ecliptic plane, have a quality that does not belong to the 'known world', like exoplanets of other star systems, like the one in the movie "Avatar" (2009), or the depths of the ocean. In general, a high inclination is related with unusual experiences, far away from day to day life.

Examples of objects with high inclination:
  • (5335) Damocles, with an inclination of 62º
  • (127546) 2002 XU93, with an inclination of 77º
  • 2004 XR190, with an inclination of 47º
  • 2008 KV42, with an absolute inclination of 76º. 


Mexican mythology

The "God's Eye" (Ojo de Dios) is a ritual tool, magical object and cultural symbol in Mexican mythology. The Huichol call their God's Eye "Sikuli", which means the power to see and understand things unknown.
