They estimate the gravity of this potential planet might explain the unusual orbits of those Kuiper objects. By analyzing these orbits, the Caltech team predicted the possibility that a large, previously undiscovered planet may be hiding far beyond Pluto. Why Do They Think It's There?Īstronomers studying the Kuiper Belt have noticed some of the dwarf planets and other small, icy objects tend to follow orbits that cluster together. Planets are traditionally named for mythological Roman gods. If the predicted world is found, the name must be approved by the International Astronomical Union. The name used during previous hunts for the long suspected giant, undiscovered object beyond Neptune is "Planet X." What is its Name?īatygin and Brown nicknamed their predicted object "Planet Nine," but the actual naming rights of an object go to the person who actually discovers it. 20 issue of the Astronomical Journal is based on mathematical modeling. Planet X has not yet been discovered, and there is debate in the scientific community about whether it exists.

It would take this new planet between 10,000 and 20,000 years to make just one full orbit around the Sun (where Neptune completes an orbit roughly every 165 years). The predicted orbit is about 20 times farther from our Sun on average than Neptune (which orbits the Sun at an average distance of 2.8 billion miles). The Caltech scientists believe Planet X may have has a mass about 10 times that of Earth and be similar in size to Uranus or Neptune.
It's the start of a process that could lead to an exciting result." What we're seeing is an early prediction based on modeling from limited observations. It's too early to say with certainty there's a so-called Planet X. "This is not, however, the detection or discovery of a new planet. "The possibility of a new planet is certainly an exciting one for me as a planetary scientist and for all of us," said Jim Green, director of NASA's Planetary Science Division. This large object could explain the unique orbits of at least five smaller objects discovered in the distant Kuiper Belt. The prediction is based on detailed mathematical modeling and computer simulations, not direct observation. In January 2015, Caltech astronomers Konstantin Batygin and Mike Brown announced new research that provides evidence of a giant planet tracing an unusual, elongated orbit in the outer solar system. Astronomers are now searching for the predicted planet. The mathematical prediction of a planet could explain the unique orbits of some smaller objects in the Kuiper Belt, a distant region of icy debris that extends far beyond the orbit of Neptune. The existence of this distant world is only theoretical at this point and no direct observation of the object nicknamed "Planet 9" have been made. The announcement does not mean there is a new planet in our solar system. It may take between 10,000 and 20,000 Earth years to make one full orbit around the Sun. The object, which the researchers have nicknamed "Planet Nine," could have a mass about 10 times that of Earth and orbit about 20 times farther from the Sun on average than Neptune. This hypothetical Neptune-sized planet orbits our Sun in a highly elongated orbit far beyond Pluto. Caltech researchers have found mathematical evidence suggesting there may be a "Planet X" deep in the solar system.
