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.
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).
Planet nine may be orbiting far from the Sun, at the edge of our solar system. Astronomers, seeing odd irregularities in the orbits of the outer planets suspect another, unknown, planet may orbit ...
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 ...
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 .
The Universe is an American documentary television series that features computer-generated imagery and computer graphics of astronomical objects in the universe plus interviews with experts who study in the fields of cosmology, astronomy, and astrophysics.
This hypothesis is now considered unlikely, since the asteroid belt has far too little mass to have resulted from the explosion of a large planet. In 2018, a study from researchers at the University of Florida found the asteroid belt was created from the fragments of at least five or six ancient planetary-sized objects instead of a single planet.
