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 largest known for a high-perihelion trans-Neptunian object (TNO), and well beyond those of (90377) Sedna and 2012 VP113. Yet, with an aphelion of 1420 ± 90 au, 2013 SY99’s orbit is interior to the region influenced by Galactic tides. Such TNOs are not thought to be produced in the current known… 
Discovery and Dynamical Analysis of an Extreme Trans-Neptunian Object with a High Orbital Inclination
We report the discovery and dynamical analysis of 2015 BP519, an extreme trans-Neptunian object (TNO) detected by the Dark Energy Survey at a heliocentric distance of 55 au, perihelion of ∼36 au, and
A New High Perihelion Trans-Plutonian Inner Oort Cloud Object: 2015 TG387
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
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
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
OSSOS. VI. Striking Biases in the Detection of Large Semimajor Axis Trans-Neptunian Objects
The accumulating but small set of large semimajor axis trans-Neptunian objects (TNOs) shows an apparent clustering in the orientations of their orbits. This clustering must either be representative
OSSOS. VII. 800+ Trans-Neptunian Objects—The Complete Data Release
The Outer Solar System Origins Survey (OSSOS), a wide-field imaging program in 2013–2017 with the Canada–France–Hawaii Telescope, surveyed 155 deg2 of sky to depths of mr = 24.1–25.2. We present 838
OSSOS. XV. Probing the Distant Solar System with Observed Scattering TNOs
TLDR
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.
Observational Bias and the Clustering of Distant Eccentric Kuiper Belt Objects
The hypothesis that a massive Planet Nine exists in the outer solar system on a distant eccentric orbit was inspired by observations showing that the objects with the most distant eccentric orbits in
OSSOS. IX. Two Objects in Neptune's 9:1 Resonance—Implications for Resonance Sticking in the Scattering Population
We discuss the detection in the Outer Solar System Origins Survey (OSSOS) of two objects in Neptune’s distant 9:1 mean motion resonance at semimajor axis a ≈ 130 au. Both objects are securely

CONSEQUENCES OF A DISTANT MASSIVE PLANET ON THE LARGE SEMIMAJOR AXIS TRANS-NEPTUNIAN OBJECTS
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
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
OBSERVATIONAL SIGNATURES OF A MASSIVE DISTANT PLANET ON THE SCATTERING DISK
The orbital element distribution of trans-Neptunian objects (TNOs) with large pericenters has been suggested to be influenced by the presence of an undetected, large planet at >200 au from the Sun.
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 Sedna-like body with a perihelion of 80 astronomical units
TLDR
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.
Stellar encounters as the origin of distant Solar System objects in highly eccentric orbits
TLDR
It is shown that a passing star probably scattered Sedna from the Kuiper belt into its observed orbit, and the likelihood that a planet at 60–80 au can be scattered into Sedna's orbit is about 50 per cent; this estimate depends critically on the geometry of the fly-by.
NEW EXTREME TRANS-NEPTUNIAN OBJECTS: TOWARD A SUPER-EARTH IN THE OUTER SOLAR SYSTEM
We are performing a wide and deep survey for extreme distant solar system objects. Our goal is to understand the high-perihelion objects Sedna and 2012 VP113 and determine if an unknown massive
EVIDENCE FOR A DISTANT GIANT PLANET IN THE SOLAR SYSTEM
Recent analyses have shown that distant orbits within the scattered disk population of the Kuiper Belt exhibit an unexpected clustering in their respective arguments of perihelion. While several
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
