 On a busy night of asteroid hunting with the 90 inch, University of Arizona’s Steward Observatory Bok telescope on Kitt Peak in Arizona, my Catalina Sky Survey teammate Vivian Carvajal discovered 13 new Earth approaching objects. One of them now known as 2025 TF immediately got her attention as it streaked through the constellation of Pegasus. Another space rock 2020 VT4 came about 30 miles closer to the surface of our home planet giving 2025 TF second place as a grazing non impactor.
