Шаблон:Short description

Шаблон:Infobox planet

Шаблон:Mp, provisionally known as Шаблон:Mp, is a temporary quasi-satellite of Neptune.[1] Observed from Neptune, it would appear to go around it during one Neptunian year but it actually orbits the Sun, not Neptune.

Discovery, orbit and physical properties

Шаблон:Mp was discovered by the Palomar Distant Solar System Survey on September 9, 2007,[2][3] with precovery images from 1988 (also taken at Palomar).[4] At the time of discovery, this minor body was believed to be a Neptune trojan,[5] but it is no longer listed as such.[6][7] The Jet Propulsion Laboratory classifies Шаблон:Mp as trans-Neptunian object but the Minor Planet Center includes the object among centaurs. It moves in an orbit with an inclination of 36.2°, a semi-major axis of 30.18 AU, and an eccentricity of 0.3020.[8] Herschel-PACS observations indicate that it has a diameter of 247 km.[9]

Quasi-satellite dynamical state and orbital evolution

Шаблон:Mp is currently following a quasi-satellite loop around Neptune.[1] It has been a quasi-satellite of Neptune for about 12,500 years and it will remain in that dynamical state for another 12,500 years.[1] Prior to the quasi-satellite dynamical state, Шаблон:Mp was an Шаблон:L5 trojan and it will go back to that state soon after leaving its current quasi-satellite orbit. Its orbital inclination is the largest among known Neptune co-orbitals. It is also possibly the largest known object trapped in the 1:1 mean-motion resonance with any major planet.

Origin

Шаблон:Mp is a dynamically hot (both, high eccentricity and inclination) object that is unlikely to be a primordial Neptune co-orbital. It probably originated well beyond Neptune and was later temporarily captured in the 1:1 commensurability with Neptune.[1][10]
