6 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 ...
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...
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.
Oct 4, 2017 · The super Earth that came home for dinner by Pat Brennan It might be lingering bashfully on the icy outer edges of our solar system, hiding in the dark, but subtly pulling strings behind the scenes: stretching out the orbits of distant bodies, perhaps even tilting the entire solar system to one side. If a […]
Jun 14, 2024 · Astronomers have been scouring the outer solar system for signs of a hypothetical ninth planet for almost a decade, without success. However, we may finally be on the cusp of finding it, experts...
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.
