Overview

• Asteroid 2025 TF flew over Antarctica at roughly 265 miles (428 km) above Earth, a height comparable to the International Space Station and among the closest approaches on record, according to ESA.
• Astronomers detected 2025 TF a few hours after the pass via the Catalina Sky Survey, with ESA follow-up using a Las Cumbres Observatory telescope to pin down its trajectory and timing.
• ESA estimates 2025 TF at about 3–10 feet (1–3 meters) across, noting such objects typically burn up as fireballs and pose no significant planetary danger.
• A separate object, 2025 TQ2, passed about 3,014 miles (4,851 km) over northern Canada the next day; the two encounters were unrelated and involved different asteroid classes.
• CNEOS lists a provisional orbital period for 2025 TF of about 2.06 years, and NASA data indicate its next close approach to Earth is not expected until April 2087.
