20,000-year orbit discovered in solar system

An icy planet with a staggering 20,000-year orbit has been discovered passing through our solar system, leading to the re-emergence of theories touting the existence of the fabled and mystical Planet 9. L91, as the icy rock is called, is an enigma defying previously established gravitational patterns, and its discovery has added to mounting evidence that there are gravitational disruptions going on beyond what we can see, according to scientists working on the Outer Solar System Origins Survey. Although L91 orbits our solar system’s sun, it never comes closer than 50 astronomical units, and at its farthest extreme it is a whopping 1,430 AU away. Each AU equals the distance between the Sun and Earth.
