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).
Kepler-9 is located in the constellation Lyra that lies some 632 parsecs away from Earth. With a mass of 1.07 M ☉ and a radius of 1.02 R ☉, Kepler-9 is almost exactly the same size and width of the Sun, being only 7% more massive and 2% wider.
Planet Nine, hypothetical ninth planet in the outer Solar System Pluto , considered the ninth planet from its 1930 discovery until it was reclassified as a dwarf planet in 2006 (except 1979–1999, see above)
Scientists say they have found new evidence that there is a hidden planet in our solar system. For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar ...
A study re-examines the evidence for a proposal first suggested in 2016 — that the hypothetical Planet 9 could explain anomalies seen by astronomers in the outer solar system.

Backyard Worlds: Planet 9 is a NASA-funded citizen science project which is part of the Zooniverse web portal. [1] It aims to discover new brown dwarfs, faint objects that are less massive than stars, some of which might be among the nearest neighbors of the Solar System, and might conceivably detect the hypothesized Planet Nine.
