Orbit

2004 XR190 is particularly unusual for two reasons. With an inclination of 47 degrees, it is the most "tilted" object discovered thus far, traveling further "up and down" than "left to right" around the Sun when viewed edge-on along the ecliptic. Second, it has an unusually circular orbit for a scattered disc object. While it has been hypothesized that traditional Scattered Disc Objects (SDOs) have been ejected into their current orbits by gravitational interactions with Neptune, the low eccentricity of its orbit and the distance of its perihelion (SDOs generally have highly eccentric orbits and perihelions less than 38 AU) seems hard to reconcile with such celestial mechanics. This has led to some uncertainty as to the current theoretical understanding of the outer Solar System. The theories include close stellar passages, rogue planets/planetary embryos in the early Kuiper belt, and resonance interaction with an outward migrating Neptune. The Kozai mechanism is capable of transferring the orbital eccentricity into an elevated inclination.[1] For the science fiction novella by William Shunn, see Inclination (novella). ... The plane of the ecliptic is well seen in this picture from the 1994 lunar prospecting Clementine spacecraft. ... A scattered disk object (or scattered disc object or SDO) is a trans-Neptunian object of the Kuiper belt with a very eccentric orbit. ... For other uses, see Neptune (disambiguation). ... This article is about the Solar System. ... A rogue planet is a planet that either has an extremely elongated orbit around its star so that it is not on the same orbital plane as the other planets in the system, or it is an interstellar planet, a planet that drifts freely through space and doesnt orbit... Protoplanets are moon-sized planet embryos within protoplanetary discs. ... In celestial mechanics, an orbital resonance occurs when two orbiting bodies exert a regular, periodic gravitational influence on each other. ... The planets of the solar system are believed to have formed out of a collapsed and spinning cloud of gas and dust. ... Planetary migration is the act of a stellar satellite altering its orbital parameters, especially semi-major axis, through various means during its lifetime. ... In celestial mechanics, the Kozai mechanism is a secular perturbative effect resulting in the periodic sychronised changes of the eccentricity and the inclination of the orbit of the perturbed body. ...
