Asteroid 2025 OM2 flew past Earth at 0.23 LD on July 19, 2025

Asteroid 2025 OM2, a near-Earth object of the Apollo orbital class, flew past Earth at a distance of 0.23 lunar distances (LD) or 0.000589 AU (88 200 km / 54 800 miles) at 18:41 UTC on July 19, 2025. The asteroid passed with a relative velocity of 20.05 km/s.

Based on its absolute magnitude (H) of 29.382, the object is estimated to be between 5 and 12 m (16 to 39 feet) in diameter. This estimation is based on standard relations for a typical near-Earth asteroid of its brightness.

Asteroid 2025 OM2 is classified as an Apollo-type asteroid, indicating it is a near-Earth object with a semi-major axis greater than Earth’s and a perihelion distance less than Earth’s aphelion. Its orbital elements are characterized by an eccentricity of 0.63, a semi-major axis of 1.46 AU, a perihelion distance of 0.542 AU, and an inclination of 4.73 degrees.

No physical parameter data such as albedo or surface classification are presently available for this object. 2025 OM2 is not classified as a potentially hazardous asteroid (PHA).

2025 OM2 was observed over a 2-day window between July 20 and July 22, 2025. The observation arc is short, and the trajectory solution currently carries a condition code of 8, indicating the orbit is uncertain or preliminary and may be subject to revision with future observations.

Several other near-Earth objects approached Earth within 1 lunar distance in July 2025. Asteroid 2025 OS passed at 0.03 LD (4 480 km / 2 784 miles) at 03:21 UTC on July 19, with an estimated diameter of 4–9 m (13–30 feet). Asteroid 2025 NH1 flew by at 0.24 LD (36 000 km / 22 400 miles) on July 4 at 23:26 UTC, estimated to be about 2–5 m (7–16 feet) in size. Asteroid 2025 NN1 made a close approach at 0.41 LD (61 400 km / 38 200 miles) on July 2 at 22:23 UTC, with an estimated size of 3–7 m (10–23 feet).
