The orbits of Sedna, 2012 VP 113, Leleākūhonua, and other very distant objects along with the predicted orbit of Planet Nine [A]. An extreme trans-Neptunian object (ETNO) is a trans-Neptunian object orbiting the Sun well beyond Neptune (30 AU) in the outermost region of the Solar System.
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).
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.
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 ...
The exploration of Jupiter — the biggest and most extreme planet in the Solar System — may change humanity's understanding of the Solar System.Recent discoveries by the National Aeronautics and Space Administration (NASA) Juno mission uncover what lies beneath Jupiter's violent storms and reveal that Jupiter is more akin to a star than a planet.
There are a large number of resonant subgroups, the largest being the twotinos (1:2 resonance) and the plutinos (2:3 resonance), named after their most prominent member, Pluto. Members of the classical Edgeworth–Kuiper belt include 15760 Albion, Quaoar and Makemake. Another subclass of Kuiper belt objects is the so-called scattering objects (SO).
In January 2016, Brown and fellow Caltech astronomer, Konstantin Batygin, proposed the existence of Planet Nine, a major planet between the size of Earth and Neptune. [11] The two astronomers gave a recorded interview in which they described their method and reasoning for proposing Planet 9 on January 20, 2016.
