On the outskirts of the solar system there are at least 17 orbiting objects, which claim to be the Ninth Planet. This conclusion was made by scientists from the United States, who studied remote celestial bodies using the latest methods of processing astronomical observations. The article appeared in The Planetary Science Journal.
It is believed that some features of the orbits of transneptune objects in the Kuiper belt can be explained solely by the existence of the ninth planet, which presumably rotates on an orbit very far from the Sun (more than 250 astronomical units). The mass of this planet should be five to ten times the mass of the Earth.
It is not yet possible to fix the “elusive” ninth planet using optical observation methods, which is not surprising, as we are talking about a very distant object. Scientists are trying to find a hypothetical planet in other ways, and the development of technology helps them.
Yale University staff, led by Malena Rice, applied the shift and overlay method, creating a program that mixed a huge array of photos from the TESS space observatory, and then combined the images, amplifying the weak light of distant objects. The method, originally designed to detect satellites of the planets in our star system, allowed us to identify 17 celestial bodies that claim to be the Ninth Planet. Now scientists have to find out, which of the objects is the “elusive” planet.
