Icy World with a Bizzare 20,000 year Orbit Discovered in Our Solar System
L91, as the icy rock is called, is an enigma defying previously established gravitational patterns.
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. This means it has a more elongated orbit than Sedna. Sedna is a distant Pluto-sized object, whose closest approach is 76 AU and whose estimated far point reaches 937 AU.
