[1] [2] The orbits of ETNOs are much less affected by the known giant planets than all other known trans-Neptunian objects. They may, however, be influenced by gravitational interactions with a hypothetical Planet Nine , shepherding these objects into similar types of orbits. [ 1 ]
Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [4] [2] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).
This list includes all numbered trans-Neptunian objects with a semi-major axis greater than 30.1 astronomical units (AU), Neptune's average orbital distance from the Sun. The data is sourced from MPC's "List of Trans Neptunian Objects" and "List Of Centaurs and Scattered-Disk Objects", in addition to MPC's "List of Neptune Trojans", completed with remarks and information from Johnston's ...
The new work represents “the strongest statistical evidence yet that Planet 9 is really out there”, he said. In the new work, scientists looked at a set of trans-Neptunian objects, or TNOs ...
Planet V, a planet thought by John Chambers and Jack Lissauer to have once existed between Mars and the asteroid belt, based on computer simulations. Various planets beyond Neptune: Planet Nine, a planet proposed to explain apparent alignments in the orbits of a number of distant trans-Neptunian objects. Planet X, a hypothetical planet beyond ...
The hypothetical Planet Nine would modify the orbits of extreme trans-Neptunian objects via a combination of effects. On very long timescales exchanges of angular momentum with Planet Nine cause the perihelia of anti-aligned objects to rise until their precession reverses direction, maintaining their anti-alignment, and later fall, returning them to their original orbits.
a dwarf planet, a cubewano, and the fourth-largest known trans-Neptunian object [30] 136199 Eris: a dwarf planet, a scattered disc object, and currently the most massive known trans-Neptunian object. It has one known satellite, Dysnomia (612911) 2004 XR 190 "Buffy" a scattered disc object following a highly inclined but nearly circular orbit ...
Planet X was previously hypothesized in a 2014 research paper. Called 2012 VP113, researchers Chadwick Trujillo and Scott Sheppard claimed that the object never came closer to the sun than 80 AU ...
