4 days ago · A giant planet with 10 Earth masses and a highly elongated orbit in the outer solar system has been discovered by mathematical modeling and computer simulations. The planet, nicknamed Planet Nine, explains the alignment and eccentricity of six distant Kuiper Belt objects and challenges the traditional view of the solar system.
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 · Astronomers propose that a large, icy planet lurks in the outer solar system, based on its gravitational influence on small objects with odd orbits. A new analysis suggests that Planet 9 could be closer, brighter, and easier to find than previously thought.
3 days ago · Planet 9, or Planet X, is a hypothetical giant planet in the outer solar system that may explain the orbits of some distant objects. Learn about the latest findings, the possible existence and the challenges of finding this elusive planet.
Oct 4, 2017 · Planet Nine is a possible super Earth in the outer solar system, whose gravitational influence explains the orbits and tilts of distant objects. Learn about the five lines of observational evidence, the search for Planet Nine, and its possible origin and fate.
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.
