New Extreme Trans-Neptunian Objects: Towards a Super-Earth in the Outer Solar System

  title={New Extreme Trans-Neptunian Objects: Towards a Super-Earth in the Outer Solar System},
  author={Scott S. Sheppard and Chadwick A. Trujillo},
  journal={arXiv: Earth and Planetary Astrophysics},
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 SR349 and 2013 FT28, are extreme detached trans-Neptunian objects, with a>150 AU and perihelia well beyond Neptune (q>40 AU). Both new objects have orbits with arguments of perihelia within the range of clustering of this angle for other extreme objects. One of these objects, 2014 SR349, has a longitude… Expand
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 forcesExpand
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
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, andExpand
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 QV 89 and 2016 QU 89 , which have orbits that appear similar to that of a previouslyExpand
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
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
A new approach to distant solar system object detection in large survey data sets
The recently postulated existence of a giant ninth planet in our solar system has sparked search efforts for distant solar system objects (SSOs) both via new observations and archival data analysis.Expand
The search for slow moving planets in the distant solar system
Out beyond the giant planets is a collection of bodies left over from planet formation. The objects that are just beyond Neptune are well studied compared to those that journey hundreds of au away;Expand
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 predictsExpand
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


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
Extreme trans-Neptunian objects and the Kozai mechanism: signalling the presence of trans-Plutonian planets.
The existence of an outer planet beyond Pluto has been a matter of debate for decades and the recent discovery of 2012 VP113 has just revived the interest for this controversial topic. ThisExpand
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
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
Extreme outer solar system objects have possible origins beyond the Kuiper Belt edge, high inclinations, very large semimajor axes, or large perihelion distances. Thirty-three such objects wereExpand
A new dynamical class of object in the outer Solar System
Some three dozen objects have now been discovered beyond the orbit of Neptune and classified as members of the Kuiper belt—a remnant population of icy planetesimals that failed to be incorporatedExpand
Exploring the outer solar system with the essence supernova survey
We report the discovery and orbital determination of 14 trans-Neptunian objects (TNOs) from the ESSENCE Supernova Survey difference imaging data set. Two additional objects discovered in a similarExpand
Constraints on the location of a possible 9th planet derived from the Cassini data
To explain the unusual distribution of Kuiper belt objects, several authors have advocated the existence of a super-Earth planet in the outer solar system. It has recently been proposed that a 10 M⊕Expand
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 theExpand
Stellar encounters as the origin of distant Solar System objects in highly eccentric orbits
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. Expand
