Asteroid 2025 UE1 will fly past Earth at 0.69 LD on October 22, 2025.

Asteroid 2025 UE1, a near-Earth object, will fly past Earth at a minimum distance of 0.69 lunar distances / 0.00177 AU (approximately 265 000 km / 164 652 miles) from the planet’s center at 23:07 UTC on October 22, 2025. The asteroid’s relative velocity at closest approach is calculated at 15.30 km/s.

Based on its absolute magnitude (H) of 26.692, the diameter of 2025 UE1 is estimated to be in the range of 14 to 32 m (46 to 105 feet), though precise dimensions depend on its albedo.

2025 UE1 is classified as an Apollo-type asteroid, characterized by its semi-major axis of 1.07 AU, perihelion distance of 0.548 AU, and an orbital eccentricity of 0.488. The inclination of its orbit is measured at 7.26 degrees. These parameters place 2025 UE1 among the typical near-Earth Apollo-group asteroids with moderately eccentric and low-inclination orbits.

No direct measurement of albedo is available for this object, but it is not classified as potentially hazardous (PHA).

The asteroid was first observed on October 15, 2025, and last observed on October 19, 2025, providing a 4-day observation arc. Its current orbit solution has a condition code of 8, indicating the trajectory is still uncertain and subject to refinement as further observations are made.

Several other asteroids have recently passed within 1 lunar distance of Earth. On October 16, 2025, asteroid 2025 UN passed at 0.45 LD; its approximate size is 6 to 13 m (20 to 43 feet). Another recent flyby included 2025 TP5 at 0.25 LD on October 15, 2025, with an estimated diameter of 14 to 32 m (46 to 105 feet). Earlier, 2025 TN5 passed at 0.35 LD on October 10, 2025, measuring roughly 9 to 20 m (30 to 66 feet).
