• Resumen

  • The outer solar system just got weirder. An object has been spotted beyond Neptune sitting above the plane of the solar system--and moving upwards. Nicknamed "Niku", which means rebellious in Chinese, the trans-Neptunian object--something that orbits beyond Neptune--is 160,000 times fainter than Neptune, making it likely to be less than 200 kilometers wide. What makes Niku such a rebel is that it's tilted 110 degrees to the plane of the solar system, meaning it swings backwards around the sun.
