Asteroid 2025 TP5 will fly past Earth at 0.25 LD on October 15, 2025

Asteroid 2025 TP5 will fly past Earth at a minimum distance of 0.25 lunar distances (LD) or 0.00065 AU, which corresponds to approximately 97 197 km (60 406 miles) from Earth’s center, at 20:09 UTC on October 15, 2025. The object will be traveling at a relative velocity of 8.36 km/s during its close approach.

Based on its absolute magnitude (H) of 26.562, asteroid 2025 TP5 is estimated to be approximately 15 to 35 m (49 to 115 feet) in diameter. This size estimate is derived from its intrinsic brightness, as no direct size measurements are presently available.

Asteroid 2025 TP5 belongs to the Apollo group of near-Earth objects, characterized by Earth-crossing orbits. Its orbital parameters include an eccentricity (e) of 0.492, a semi-major axis (a) of 1.89 AU, a perihelion distance (q) of 0.961 AU, and an inclination (i) of 1.47 degrees. This orbit is moderately eccentric and typical of small Apollo-class asteroids.

No direct physical property measurements such as albedo are currently available for this object. It is not classified as potentially hazardous (PHA).

2025 TP5 was first observed on October 13, 2025, and most recently observed on October 14, 2025, giving a short observation arc of two days. The current orbit solution carries a condition code of 6, indicating the orbital parameters are uncertain or preliminary.

Several other near-Earth objects have recently passed within 1 lunar distance of Earth. These include asteroid 2025 TC, which flew past Earth at 0.22 LD (33 991 km / 21 132 miles) at 06:34 UTC on October 3, 2025. Asteroid 2025 TQ2 made a close approach at 0.03 LD (4 494 km / 2 793 miles) at 19:02 UTC on October 2, 2025. Additionally, asteroid 2025 TP passed by at 0.28 LD (43 081 km / 26 785 miles) at 21:17 UTC on October 1, 2025.
