Explaining the origin of the orbits of 2000 CR105 (a = 230 AU, q = 44 AU) and 2003 VB12 (a = 531 AU, q = 74 AU, unofficially known as Sedna) is a major test for our understanding of the primordial evolution of the outer solar system. Gladman et al. have shown that 2000 CR105 could not have been a normal member of the scattered disk that had its perihelion distance increased by chaotic diffusion. The same conclusion also clearly applies to 2003 VB12. In this paper, we explore five seemingly…

Towards an explanation of orbits in the extreme trans-Neptunian region: The effect of Milgromian dynamics

Milgromian dynamics (MD or MOND) uniquely predicts motion in a galaxy from the distribution of its stars and gas in a remarkable agreement with observations so far. In the solar system, MD predicts

The Generation of the Distant Kuiper Belt by Planet Nine from an Initially Broad Perihelion Distribution

The observation that the orbits of long-period Kuiper Belt objects (KBOs) are anomalously clustered in physical space has recently prompted the Planet Nine hypothesis—the proposed existence of a

OSSOS. V. Diffusion in the Orbit of a High-perihelion Distant Solar System Object

We report the discovery of the minor planet 2013 SY99 on an exceptionally distant, highly eccentric orbit. With a perihelion of 50.0 au, 2013 SY99’s orbit has a semimajor axis of 730 ± 40 au, the


Trans-Neptunian objects (TNOs) are remnants of a collisionally and dynamically evolved planetesimal disk in the outer solar system. This complex structure, known as the trans-Neptunian belt (or


We explore the distant giant planet hypothesis by integrating the large-semimajor-axis, large-pericenter trans-Neptunian objects (TNOs) in the presence of the giant planets and an external perturber

How Sedna and family were captured in a close encounter with a solar sibling

The discovery of 2012VP113 initiated the debate on the origin of the Sedna family of planetesimals in orbit around the Sun. Sednitos roam the outer regions of the Solar System between the

A Low-inclination Neutral Trans-Neptunian Object in an Extreme Orbit

We present photometric observations and numerical simulations of 2016 SD106, a low-inclination (i = 4.°8) extreme trans-Neptunian Object with a large semimajor axis (a = 350 au) and perihelion (q =

Peculiar orbits and asymmetries in extreme trans-Neptunian space

It is still an open question how the Solar system is structured beyond 100 au from the Sun. Our understanding of this vast region remains very limited and only recently we have become aware of the

Regarding the Accretion of 2003 VB12 (Sedna) and Like Bodies in Distant Heliocentric Orbits

Recently, Brown et al. reported the exciting discovery of an ∼800 km radius object, (90377) Sedna, on a distant, eccentric orbit centered at ∼490 AU from the Sun. Here we undertake a first look



The Existence of a Planet beyond 50 AU and the Orbital Distribution of the Classical Edgeworth–Kuiper-Belt Objects

Abstract We study the effects of a Mars-like planetoid with a semimajor axis at about ∼60 AU orbiting embedded in the primordial Edgeworth–Kuiper belt (EKB). The origin of such an object can be

A new class of trans-Neptunian objects in high-eccentricity orbits

A symplectic integrator is used to study the evolution of high-eccentricity trans-Neptunian objects (TNOs) over the age of the Solar system. For 26 objects, a few cloned orbits were integrated. We

Evidence for an Extended Scattered Disk

Abstract By telescopic tracking, we have established that the transneptunian object (TNO) 2000 CR 105 has a semimajor axis of 220±1 AU and perihelion distance of 44.14±0.02 AU, beyond the domain

The origin of the Kuiper Belt high-inclination population

A disk of scattered icy objects and the origin of Jupiter-family comets.

Two recently discovered objects, 1996 RQ20 and 1996 TL66, have orbital elements similar to those predicted for objects in this disk, suggesting that they are thus far the only members of this disk to be identified.

On the Collisional Environment, Accretion Time Scales, and Architecture of the Massive, Primordial Kuiper Belt.

ii Abstract Previous collisional modelling has suggested that the mass of the primordial Kuiper Disk between 30 and 50 AU was probably of order 10M to 50M. We explore the consequences of a massive,

Evidence for Early Stellar Encounters in the Orbital Distribution of Edgeworth-Kuiper Belt Objects

We show that early stellar encounters can explain the high eccentricities and inclinations observed in the outer part (>42 AU) of the Edgeworth-Kuiper Belt (EKB). We consider the proto-Sun as a

Large Scattered Planetesimals and the Excitation of the Small Body Belts

Abstract We study the dynamical excitation that large planetesimals, scattered either by Neptune or Jupiter, could have provided to the primordial Edgeworth–Kuiper belt and the asteroid belt. Using

Abstract We present numerical orbital integrations of thousands of massless particles as they evolve from Neptune-encountering orbits in the Kuiper belt for up to 1 Gyr or until they either impact a
