Astronomers from NASA and the University of Berkeley (USA) estimate the possibility that there is a nineth planet in our galaxy.

NASA astronomers, Arizona State University and Berkeley University are trying to locate a strange object lost in the space between the Sun and the nearest stars. It is called Planet X or Planet 9, which would be the ninth planet in the Solar System, whose existence scientists have found evidence. Now, they ask citizens to participate in the search. The online project is called “Backyard Worlds: Planet 9” and uses images taken by NASA’s WISE space telescope. Volunteers will have access to the set of animated photographs in search of moving objects. One of them could be the mysterious world.
Scientists believe that there is a ninth planet due to the behavior of the orbits of objects in the Kuiper belt, an area of cometary-like bodies orbiting the Sun beyond the orbit of Neptune. The Kuiper belt is similar to the asteroid belt that surrounds the Sun between Mars and Jupiter, but is dozens of times farther away.
This hypothetical Planet 9 could be similar in size to Neptune, but it can orbit up to a thousand times farther from the Sun than Earth. For that reason, they argue, while astronomers can see its effects on objects in the Kuiper Belt, so far no one has been able to observe it directly.
“If it exists, Planet 9 could be big, maybe 10 times the mass of Earth. However, it must be very thin and difficult to find, “explains Adam Schneider, researcher at the Arizona State.
In addition to the search for a distant planet in orbit around the Sun, this new project will help astronomers identify the closest neighbors to the Sun outside of our Solar System. “There is just over four light years between Neptune and Proxima Centauri, the closest star, and much of this vast territory is unexplored,” says Marc Kuchner, an astrophysicist at NASA’s Goddard Space Flight Center.
