We report the discovery of a minor planet (2006 SQ372) on an orbit with a perihelion of 24 AU and a semimajor axis of 796 AU. Dynamical simulations show that this is a transient orbit and is unstable on a timescale of ~200 Myr. Falling near the upper semimajor axis range of the scattered disk and the lower semimajor axis range of the Oort Cloud, previous membership in either class is possible. By modeling the production of similar orbits from the Oort Cloud as well as from the scattered disk…

Reassessing the Source of Long-Period Comets
Numerical simulations show that the inner Oort Cloud is a major source of long-period comets that cross Earth’s orbit, and they are an important, if not the dominant, source of known LPCs.
An Oort cloud origin of the Halley-type comets
The origin of the Halley-type comets (HTCs) is one of the last mysteries of the dynamical evolution of the Solar System. Prior investigation into their origin has focused on two source regions: the
Orbital Precession in the Distant Solar System: Further Constraining the Planet Nine Hypothesis with Numerical Simulations
The longitudes of perihelia and orbital poles of the solar system's dozen or so most remote detected objects are clustered in a manner inconsistent with that of a random sample of uniformly
Discovery of a New Member of the Inner Oort Cloud from the Next Generation Virgo Cluster Survey
We report the discovery of 2010 GB174, a likely new member of the Inner Oort Cloud (IOC). 2010 GB174 is 1 of 91 trans-Neptunian objects and Centaurs discovered in a 76 deg2 contiguous region imaged
Where do long‐period comets come from? Moving through the Jupiter–Saturn barrier
The past and future dynamical evolution of all 64 long-period comets having 1/aori 3.0 au and discovered after 1970 is studied. For this sample of Oort-spike comets we have obtained a new,
It is confirmed that observed scattering objects cannot solely originate from the classical Kuiper belt, and it is shown that both the Oort cloud and a distant planet generate observable highly inclined scatterers.
Stability of Neptune’s Distant Resonances in the Presence of Planet Nine
Trans-Neptunian Objects (TNOs) in the scattered disk with 50 ≲ a ≲ 100 au are thought to cluster near Neptune’s n:1 resonances (e.g., 3:1, 4:1, and so on). While these objects spend lengthy periods
Dynamical Population of Comet Reservoirs
The Oort cloud and the scattered disk are the two primary reservoirs for long-period and short-period comets, respectively. In this review, we assess the known observational constraints on these


Discovery of a Candidate Inner Oort Cloud Planetoid
We report the discovery of the minor planet (90377) Sedna, the most distant object ever seen in the solar system. Prediscovery images from 2001, 2002, and 2003 have allowed us to refine the orbit
Comet showers and the steady-state infall of comets from the Oort cloud
The appearance of an inner edge to the Oort comet cloud at a semimajor axis of a = (1--2) x 10/sup 4/ AU is an observational artifact. Stellar perturbations are frequent enough and strong enough to
Centaurs from the Oort cloud and the origin of Jupiter-family comets
A numerical study of an ensemble of orbits based on observed objects in the near-Neptune high-eccentricity (NNHE) region, with perihelion distances q in the range 28 60 au being roughly an order of
The Scattered Disk as the Source of the Jupiter Family Comets
The short-period Jupiter family comets (JFCs) are thought to originate in the Kuiper Belt; specifically, a dynamical subclass of the Kuiper Belt known as the "scattered disk" is argued to be the
The fundamental role of the Oort cloud in determining the flux of comets through the planetary system
A model of the Oort cloud has been developed by accounting for planetary, stellar and Galactic perturbations using numerical symplectic integrations covering 4.5 Gyr. The model is consistent with the
The Origin of Halley-Type Comets: Probing the Inner Oort Cloud
We have integrated the orbits of 27,700 test particles initially entering the planetary system from the Oort cloud in order to study the origin of Halley-type comets (HTCs). We included the
Injection of Oort Cloud comets: the fundamental role of stellar perturbations
We present Monte Carlo simulations of the dynamical evolution of the Oort cloud over the age of the Solar System, using an initial sample of one million test comets without any cloning. Our model
Embedded star clusters and the formation of the Oort Cloud
The Evolution of Long-Period Comets
We study the evolution of long-period comets by numerical integration of their orbits, a more realistic dynamical approach than the Monte Carlo and analytic methods previously used to study this
