The presence, the physical and dynamical properties, the chemical composition and the possible origin of Trans Neptunians small bodies are reviewd. The enrichment of dust by collisions among TNOs in the Kuiper Belt is also discussed.

Surveys in Geophysics, 1997
Since the periodicity of comets was first established by Halley, the question of their origin has fascinated astronomers. It is clear that they have to be stored somewhere, since their life time in the inner Solar System is short. Around 1950 the idea emerged that cometary nuclei could be stored in a belt beyond Neptune, and this belt became known as ...

Trans-neptunian objects (TNOs) are believed to be pristine remnants of planets formation, providing constrains on the early stages of the solar system evolution. The knowledge of this population composition and dynamics provides constrains on the formation processes of the early solar nebula, as well as formation processes of other planetary systems ...

HST Photometry of trans-Neptunian Objects
Earth, Moon, and Planets, 2003From July 2001 to June 2002, an HST snapshot program obtained V, R and I photometry for 72 TNOs. The TNOs were sorted by dynamical class, and Spearman rank correlation statistics were calculated for each combination of color and orbital parameter. No strong correlations were found for the combined sample of TNOs, the resonant TNOs, or the non-resonant ...

The trans-neptunian objects (TNOs) constitute a new class of solar system object that was discovered only recently to exist beyond the orbit of Neptune. About 400 trans-neptunian objects have been detected over the past nine years and more than ten new objects are being discovered every month.

Satellites play a crucial role in understanding the formation and evolution of trans‐Neptunian objects (TNOs). The spin–orbit evolution of satellite systems depends on their thermal histories, allowing us to constrain the rock mass fraction within TNOs ...

Trans-Neptunian Object discoveries at KMTNet-CTIO
2022<p>We report a multi-opposition discovery of 17 Trans-Neptunian Objects (TNOs) with the Chilean node of the Korea Microlensing Telescope Network (KMTNet-CTIO) which has a 1.6 m wide-field optical telescope covering 2x2 square degree field of view. The first survey observations were made with 4 fields around (RA,DEC = 197.6&#176;, -
