is an extreme trans-Neptunian object and List of possible dwarf planets, dwarf planet candidate, estimated to be at least in diameter. It was announced in 2025 by Sihao Cheng, Jiaxuan Li, and Eritas Yang, who discovered the object in archived telescope images from 2011 to 2018. With an absolute magnitude of between 3 and 4, may be the List_of_possible_dwarf_planets#Brightest_unmeasured_candidates, brightest known object in the Solar System that does not have a directly measured size. The orbit of is extremely large and eccentric orbit, elongated, bringing it from away from the Sun. Discovery was discovered by a team at the Institute for Advanced Study led by Sihao Cheng and two Princeton University students, Jiaxuan Li, and Eritas Yang, in a search for trans-Neptunian objects (TNOs) in archived Dark Energy Camera Legacy Survey (DECaLS) images in the hope of finding the hypothetical Planet Nine. Cheng claimed that he became inspired to survey the deep solar system after ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada–France–Hawaii Telescope
The Canada–France–Hawaii Telescope (CFHT) is located near the summit of Mauna Kea mountain on Hawaii's Big Island at an altitude of 4,204 meters (13,793 feet), part of the Mauna Kea Observatory. Operational since 1979, the telescope is a Prime Focus/ Cassegrain configuration with a usable aperture diameter of . CFHT is currently considering a refurbishment to the facility in the 2020s. The facility would be reconstructed with a new 11-meter telescope to produce the Maunakea Spectroscopic Explorer, retaining the same base building and infrastructure. First light is expected no earlier than 2029. Funding The corporation is bound by a tripartite agreement between the University of Hawaii at Manoa, in the United States, the National Research Council (NRC) in Canada and the Centre National de la Recherche Scientifique (CNRS) in France. CFHT also has partnerships with the National Astronomical Observatory of China (NAOC), the Academia Sinica Institute of Astronomy and Astrophy ...
