Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [2] [4] 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).
A ninth planet is one form the solar system’s mysterious mass could take. After centuries of watching the skies, the map of our local solar system has grown quite detailed. In the impenetrable ...
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 ...
Michael E. Brown (born June 5, 1965) is an American astronomer, who has been professor of planetary astronomy at the California Institute of Technology (Caltech) since 2003. [1] His team has discovered many trans-Neptunian objects (TNOs), including the dwarf planet Eris , which was originally thought to be bigger than Pluto , triggering a ...
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.

As of 2024, no large planet has been found beyond Neptune that would explain any alleged discrepancy, despite the discovery of trans-Neptunian objects (most notably, Pluto). While the astronomical community widely agrees that "Planet X", as originally envisioned, does not exist, the concept of an as-yet-unobserved planet has been revived by a ...
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 ...
