Planet 9 hunters are searching the edge of our solar system for this mysterious world, and a tiny dwarf planet may finally lead to its discovery.
Why Can’t We Find Planet Nine?
“Astronomers suspect that there’s a large planet hiding out in the distant fringes of the solar system. At a recent workshop, they brainstormed ways to coax it into view.”
The Search For Planet X Gets a Boost With the Discovery of a Super Distant Object
“A new discovery is strengthening the idea that a large, mysterious planet — known as Planet 9 or Planet X — may be lurking unseen at the Solar System’s edge. Astronomers say they have found a tiny object orbiting far out from the Sun that fits with the Planet X theory.”
“Caltech researchers have found mathematical evidence suggesting there may be a "Planet X" deep in the solar system. This hypothetical Neptune-sized planet orbits our Sun in a highly elongated orbit far beyond Pluto.”
