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).
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 ...

The missing Planet Nine is lurking somewhere in our solar system, and we're one step closer to discovering it. See why scientists think they can find Planet 9.
2015 BP 519 fits into the group of extreme trans-Neptunian objects that originally led to the prediction of Planet Nine. [a]: 13 The group consists of more than a dozen bodies with a perihelion greater than 30 AU and a semi-major axis greater than 250 AU, with 2015 BP 519 having the highest orbital inclination of any of these objects.
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 .
2010 GB 174 has the third highest Tisserand parameter relative to Jupiter of any Trans-Neptunian object, after Sedna and 2012 VP 113. It has not been observed since 2015. [1] It comes to opposition in late March each year in the constellation of Virgo. Precovery images have been found back to 26 June 2009. [1]
The possible existence of a mystery planet has long been debated, but astronomers from Spain just released a new paper reaffirming its presence. New evidence supports the existence of Planet Nine ...
