5 days ago · Caltech Researchers Find Evidence of a Real Ninth Planet. Written by Kimm Fesenmaier Source CalTech. This artistic rendering shows the distant view from Planet Nine back towards the sun. The planet is thought to be gaseous, similar to Uranus and Neptune. Hypothetical lightning lights up the night side.
Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. 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. These ETNOs tend to make ...

5 days ago · Some call the potential celestial object Planet X and some call it Planet 9 — as in, the ninth planet in our solar system now that Pluto has been demoted to a dwarf planet. But by any name, the interest is clearly high.
May 1, 2024 · Scientists have been searching for a ninth planet to explain the orbital eccentricities of Uranus and Neptune (and dwarf planets like Sedna and Pluto) for more than a century.
Apr 30, 2024 · — Elusive Planet 9 could be surrounded by hot moons, and that's how we'd find it — Renowned string theorist proposes new way to hunt our solar system's mysterious 'Planet 9'
Apr 23, 2024 · A small team of planetary scientists from the California Institute of Technology, Université Côte d'Azur and Southwest Research Institute reports possible new evidence of Planet 9. They have ...
Aug 31, 2021 · Planet 9 may be closer and easier to find than thought—if it exists. A new study's "treasure map" suggests that a planet several times more massive than Earth could be hiding in our solar...
Mar 1, 2024 · March 01, 2024. We get a lot of exciting science news about new exoplanets routinely discovered by powerful space telescopes — the planets that orbit stars other than our own Sun. But you might be surprised to know that the search for a new planets in our own solar system is ongoing.
Jan 20, 2016 · Unlike the class of smaller objects now known as dwarf planets, Planet Nine gravitationally dominates its neighborhood of the solar system. In fact, it dominates a region larger than any of the other known planets – a fact that Brown says makes it "the most planet-y of the planets in the whole solar system."
