Inner Oort Cloud objects (IOCs) are Trans-Plutonian for their entire orbits. They are beyond the strong gravitational influences of the known planets yet close enough to the Sun that outside forces are minimal. Here we report the discovery of the third known IOC after Sedna and 2012 VP113, called 2015 TG387. 2015 TG387 has a perihelion of $65 \pm 1$ au and semi-major axis of $1170 \pm 70$ au. The longitude of perihelion angle, $\bar{\omega}$, for 2015 TG387 is between that of Sedna and 2012… Expand
Outer Solar System Perihelion Gap Formation through Interactions with a Hypothetical Distant Giant Planet
Among the outer solar system minor planet orbits there is an observed gap in perihelion between roughly 50 and 65 au at eccentricities e ≳ 0.65. Through a suite of observational simulations, we showExpand
Injection of Inner Oort Cloud Objects into the Distant Kuiper Belt by Planet Nine
The outer solar system exhibits an anomalous pattern of orbital clustering, characterized by an approximate alignment of the apsidal lines and angular momentum vectors of distant, long-term stableExpand
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 uniformlyExpand
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. Expand
No Evidence for Orbital Clustering in the Extreme Trans-Neptunian Objects
The apparent clustering in longitude of perihelion ϖ and ascending node Ω of extreme trans-Neptunian objects (ETNOs) has been attributed to the gravitational effects of an unseen 5–10 Earth-massExpand
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 theExpand
A Pluto–Charon Sonata: Dynamical Limits on the Masses of the Small Satellites
During 2005-2012, images from Hubble Space Telescope (HST) revealed four moons orbiting Pluto-Charon (Weaver et al 2006, Showalter et al 2011, 2012). Although their orbits and geometric shapes areExpand
Transneptunian Space and the Post-Pluto Paradigm
The Pluto system is an archetype for the multitude of icy dwarf planets and accompanying satellite systems that populate the vast volume of the solar system beyond Neptune. New Horizons’ explorationExpand
An attempt to constrain Planet Nine’s orbit and position via resonant confinement of distant TNOs
We considered four TNOs on elongated orbits with small semimajor axis uncertainties: Sedna, 2004 VN112, 2012 VP113, and 2000 CR105. We found two sets of simultaneous near commensurabilities for theseExpand
Observational constraints on an undiscovered giant planet in our solar system
Abstract Over the last few years, the action of an undiscovered giant planet has been considered in many works to explain the orbital properties of the most distant known objects in our solar system.Expand


New Extreme Trans-Neptunian Objects: Towards a Super-Earth in the Outer Solar System
We are conducting a survey for extreme solar system objects to understand Sedna and 2012 VP113 and determine if an unknown massive planet exists in the outer solar system. Two new objects, 2014 SR349Expand
Beyond the Kuiper Belt Edge: New High Perihelion Trans-Neptunian Objects with Moderate Semimajor Axes and Eccentricities
We have been conducting a survey for distant solar system objects beyond the Kuiper Belt edge (~50 AU) with new wide-field cameras on the Subaru 8 meter and CTIO 4 meter telescopes. We are interestedExpand
A Sedna-like body with a perihelion of 80 astronomical units
The detection of 2012 VP113 confirms that Sedna is not an isolated object; instead, both bodies may be members of the inner Oort cloud, whose objects could outnumber all other dynamically stable populations in the Solar System. Expand
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 orbitExpand
2006 SQ372: A Likely Long-Period Comet from the Inner Oort Cloud
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 unstableExpand
Re-assessing the formation of the inner Oort cloud in an embedded star cluster – II. Probing the inner edge
The detached object Sedna is likely at the inner edge of the Oort cloud, more precisely the inner Oort cloud (IOC). Until recently it was the sole member of this population. The recent discovery ofExpand
We explore the distant giant planet hypothesis by integrating the large semi-major axis, large pericenter Trans-Neptunian Objects (TNOs) in the presence of the giant planets and an external perturberExpand
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. Expand
