Overview

• NASA’s Asteroid Watch dashboard logged five near-Earth approaches between July 25 and July 28, with 2025 OF2, 2025 OU1 and 2025 OX already cleared without incident.
• Asteroid 2025 OW, measuring about 64 meters in diameter, is due to pass at a distance of 632,000 kilometers (1.6 lunar distances) on July 28.
• The smaller 2018 BE5, roughly 43 meters across, will fly by on the same day at approximately 4.1 million kilometers from Earth.
• Precise orbit determinations by JPL’s CNEOS show that none of these asteroids meets NASA’s potentially hazardous criteria of exceeding 150 meters in diameter or approaching within 7.5 million kilometers.
• Scientists note that objects the size of 2025 OW impact Earth only once every 10,000 years on average, highlighting the effectiveness of ongoing planetary defense monitoring.
