My Catalina Sky Survey teammate Hannes Gröller was asteroid hunting in the constellation of Ursa Major with the University of Arizona 90 inch Bok telescope on Kitt Peak when he discovered a faint moving object surrounded by a tiny gas and dust cloud called a coma. May 19, 2028 comet C/2025 D1 (Groeller) reaches its closest point to the Sun some 14.1 times the Earth-Sun distance and thus sets the record for the comet which stays furtherest from the Sun.After rounding the Sun comet C/2025 D1 (Groeller) will head back into truly deep space perhaps never to return.
