The new solar system object, orbiting behind Neptune, has been spotted by Vatican astronomers. Space object 2021 XD7 makes a full circle around the Sun in 286 years. Its dimensions are presumably smaller than the dwarf planet Pluto. As mir24 notes, the orbit of 2021 XD7 has an unusual shape and is titled much more than that of Earth and Mars. According to scientists, thanks to this feature, they will be able to find the mysterious Ninth Planet, since changes in the orbits of trans-Neptunian bodies are associated with the gravity of an object. It is assumed that the unknown planet is about four times the size of the Earth, and a complete revolution around the Sun in an extremely elongated orbit should take from 10 to 20 thousand years. According to preliminary calculations, the Ninth planet is located at a distance of 46,5 billion miles from the Sun (74,8 billion km).
