Overview

• Asteroid 2025 PM2, roughly 190 feet (58 meters) across, makes its closest approach on August 27 at about 2.31 million miles from Earth at nearly 41,000 mph.
• On August 26, 2025 QB5 (~80 feet) passed within about 2.79 million miles at 10,668 mph, 2025 QK3 (~120 feet) within about 2.81 million miles at 28,457 mph, and 2025 QB3 (~65 feet) within about 4.5 million miles at 15,739 mph.
• Also on August 27, asteroid 2025 QC1, about 66 feet wide, is passing at roughly 1 million miles, according to NASA’s close-approach data.
• NASA’s Planetary Defense Coordination Office and JPL’s CNEOS report well-determined orbits and no threat, with the agency classifying objects as potentially hazardous only if they are about 150 meters or larger and can approach within roughly 4.6 million miles.
• CNEOS listings show additional safe flybys later this week, including asteroids 2025 PX and 2025 QY4 on August 29 at approximately 6.31 million kilometers and 4.51 million kilometers respectively, with no collision risk.
