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 absolute magnitude Hr = 4.3. The current orbit, determined from a 1110 day observational arc, has a semimajor axis a ≈ 450 au, eccentricity e ≈ 0.92, and inclination i ≈ 54°. With these orbital elements, 2015 BP519 is the most extreme TNO discovered to date, as quantified by the reduced Kozai… 
Dynamical Analysis of Three Distant Trans-Neptunian Objects with Similar Orbits
This paper reports the discovery and orbital characterization of two extreme trans-Neptunian objects (ETNOs), 2016 QV89 and 2016 QU89, which have orbits that appear similar to that of a previously
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-mass
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
Testing the Isotropy of the Dark Energy Survey’s Extreme Trans-Neptunian Objects
We test whether the population of “extreme” trans-Neptunian objects (eTNOs) detected in the first four years of the Dark Energy Survey (DES Y4) data exhibit azimuthal asymmetries that might be
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
The Secular Dynamics of TNOs and Planet Nine Interactions
The existence of Planet Nine has been suggested to explain the pericenter clustering of extreme trans-Neptunian objects (TNOs). However, the underlying dynamics involving Planet Nine, test particles,
The Influence of Planet Nine on the Orbits of Distant TNOs: The Case for a Low-perihelion Planet
The hypothesis of an additional planet in the outer solar system has gained new support as a result of the confinement noted in the angular orbital elements of distant trans-Neptunian objects.
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
