Asteroid 2025 QO7 will fly past Earth at 0.71 LD on August 31, 2025

Asteroid 2025 QO7, a near-Earth object belonging to the Apollo class, will fly past Earth at a minimum distance of 0.71 lunar distances / 0.00183 AU (274 000 km / 170 000 miles) at 14:09 UTC on August 31, 2025. Its approach velocity relative to Earth is estimated at 8.17 km/s.

Based on its absolute magnitude (H) of 26.6, 2025 QO7 is estimated to be approximately 16 to 23 m (52 to 75 feet) in diameter. Size estimates remain subject to observational uncertainties and assumptions about its albedo.

2025 QO7 follows an Apollo-type orbit with an eccentricity of 0.419 and a semi-major axis of 1.62 AU. Its perihelion distance is 0.944 AU and its orbital inclination is 2.4 degrees. These parameters are typical of near-Earth asteroids and do not indicate a highly inclined or unusually eccentric path.

Physically, 2025 QO7 is not classified as potentially hazardous, as it does not meet the criteria for size and approach distance imposed by planetary defense guidelines. Its albedo is not directly measured; thus, no precise compositional inference can be drawn from current data.

2025 QO7 was first observed on August 26, 2025, and most recently on August 27, 2025, resulting in an extremely short observational arc of 1 day. The orbit solution currently has a condition code of 8, indicating a high degree of uncertainty that will likely decrease as additional data become available.

Other recent close approaches within 1 lunar distance include Asteroid 2025 QM3, which passed at 0.53 LD (81 000 km / 50 000 miles) at 12:00 UTC on August 21, 2025. Asteroid 2025 PF2 made a very close transit at 0.06 LD (9 000 km / 5 600 miles) at 00:13 UTC on August 15, 2025. These objects were generally much smaller, with estimated diameters well below those of 2025 QO7.
