Overview

• Astronomers report 2025 TF passed about 266 miles (428 kilometers) above Antarctica on Sept. 30, an altitude comparable to the International Space Station.
• ESA described the pass as one of the closest approaches ever recorded, with follow-up observations from the Las Cumbres Observatory refining its path and timing.
• The Catalina Sky Survey detected 2025 TF a few hours after closest approach, and CNEOS/JPL lists an approximate orbital period near 2.06 years based on limited data.
• ESA estimates 2025 TF at roughly 1–3 meters across, noting such objects pose no significant danger but can create bright fireballs or drop small meteorites.
• A separate small asteroid, 2025 TQ2, was detected shortly before its Oct. 2 flyby over northern Canada at about 3,014 miles (4,851 kilometers), and the two objects are unrelated.
