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).
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. [12]
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 ...
Nonetheless, an article in the British tabloid The Sun (later republished in the New York Post) [124] conflated the three ideas of Nibiru, Planet Nine, and Whitmire's planet to suggest that not only had Planet Nine been found, but that it would collide with Earth at the end of April, which resulted in Batygin receiving a spike in panicked calls ...
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 ...
In January, researchers Mike Brown and Konstantin Batygin proposed that a possible ninth planet was orbiting on the outer edge of the solar system. There's even more evidence Planet Nine is hiding ...
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.
