A newly discovered asteroid designated 2025 TP2 will fly past Earth at a distance of 0.25 LD (0.00065 AU / 97 158 km / 60 371 miles) from the center of our planet at 20:08 UTC on October 15, 2025.
This is the 125th known asteroid to fly past Earth since the start of the year and the 8th so far this month. 26 such objects flew past us during the month of September.
2025 TP2 was first observed at ATLAS-MLO, Mauna Loa, Hawaii, on October 13, 2025 — two days before its close approach to Earth.
The object belongs to the Apollo group of asteroids and has an estimated diameter between 13 and 30 m (43 to 98 feet). This is comparable to the object that disintegrated over Chelyabinsk, Russia, on February 15, 2013, damaging more than 7 000 buildings and injuring about 1 500 people.
At the time of its closest approach, 2025 TP2 is expected to travel at a relative velocity of about 8.37 km/s (5.2 mi/s) with respect to Earth. Shortly after that, at 09:25 UTC on October 16, it will pass the Moon at a distance of 0.00080 AU (119 640 km / 74 340 miles).
According to data from NASA’s Center for Near-Earth Object Studies (CNEOS), 2025 TP2 follows a moderately elongated orbit with an eccentricity of 0.49, a semi-major axis of 1.89 AU, and an inclination of 1.47°. Its Earth Minimum Orbit Intersection Distance (MOID) is 0.000603 AU (90 200 km / 56 000 miles), placing it within the range of close-approaching near-Earth objects. The orbital period is approximately 2.6 years.
