JWST mid-infrared spectroscopy of centaurs and small trans-Neptunian objects: Linking the inner and outer Solar System

Astronomy & Astrophysics
A fraction of the small bodies that formed in the outer Solar System (beyond Uranus and Neptune) are predicted to have been implanted in the inner Solar System (P- and D-type asteroids and Jupiter trojans) following the outward migration of these two ...

Measuring the degree of clustering and diffusion of trans-Neptunian objects

Icarus (New York, N.Y. 1962)
The outer solar system is populated by a broad aggregate of minor bodies, which occupy orbits whose dynamical character ranges from long-term stable to rapidly diffusive.

Year six photometric measurements of known Trans-Neptunian Objects and Centaurs by the Dark Energy Survey

Monthly notices of the Royal Astronomical Society
We identified known Trans-Neptunian Objects (TNOs) and Centaurs in the complete Dark Energy Survey (DES) year six catalog (DES Y6) through the Sky Body Tracker (SkyBoT) tool. We classified our dataset of 144 objects into a widely used 4-class taxonomic

Resonant Periodic Orbits of Trans-Neptunian Objects

Earth, Moon, and Planets, 2002
We study two and three-dimensional resonant periodic orbits, usingthe model of the restricted three-body problem with the Sun andNeptune as primaries. The position and the stability character ofthe periodic orbits determine the structure of the phase space andthis will provide useful information on the stability and longterm evolution of trans ...

Trans-Neptunian Objects

2016
For a very long period of time our solar system was believed to comprise nine planets: the terrestrial planets Mercury, Venus, Earth, Mars, followed by the gas giants Jupiter, Saturn, Uranus and Neptune. The exotic and tiny Pluto brought up the rear. Pluto was demoted from its planet status in 2006. Thus, only eight planets remain.

The trans-neptunian object UB313 is larger than Pluto

Nature, 2006
The most distant known object in the Solar System, 2003 UB313 (97 au from the Sun), was recently discovered near its aphelion. Its high eccentricity and inclination to the ecliptic plane, along with its perihelion near the orbit of Neptune, identify it as a member of the 'scattered disk'.

Multicolor Photometry of Trans-neptunian Objects

Icarus, 2001
Abstract We are continuing our photometric survey of the trans-neptunian and Centaur populations started in 1997. We report multicolor photometry for 17 objects. With these results combined with previous data (M. A. Barucci, A. Doressoundiram, M. Fulchignoni, D. Tholen, and M. Lazzarin 1999. Icarus 142 , 476–481; M. A. Barucci, J.

Serendipitous occultations by sub-kilometer-sized trans-Neptunian objects with MIOSOTYS - I

Monthly notices of the Royal Astronomical Society
We present here the first 4-year (2010-2013) campaign of the search for sub-kilometer-sized trans-Neptunian objects using serendipitous method with a dedicated ground-based instrument miosotys (Multi-object Instrument for Occultations in the SOlar ...

A Review of Mission Architectures for the Exploration of Trans-Neptunian Objects

JBIS - Journal of the British Interplanetary Society
Only two Trans-Neptunian Objects have been visited to date, Pluto and Arrokoth, both encountered on flybys during the New Horizons mission. There are now over 5,000 known bodies in this distant region of the Solar System.

Early formation of moons around large trans-Neptunian objects via giant impacts

Nature Astronomy, 2019
Recent studies1,2 have revealed that all large (over 1,000 km in diameter) trans-Neptunian objects (TNOs) form satellite systems. Although the largest Plutonian satellite, Charon, is thought to be an intact fragment of an impactor directly formed via a ...
