Today, NASA tracked a rare celestial event as three asteroids cruised past Earth, with the largest measuring a whopping 1,300 feet across—roughly the size of an aircraft carrier. None posed any danger to our planet, but the cosmic close shave gives scientists a valuable opportunity to study these ancient space rocks up close. The space visitors included asteroid 424482 (2008 DG5), approximately 320-700 meters wide, which passed Earth at 23:59 UTC at a distance of about 3.5 million kilometers (9 times the average lunar distance). Alongside it, two smaller rocks—2025 LD (73 feet) traveling at roughly 15,000 mph (6.7 km/s) … Continue reading NASA Tracks Trio of Asteroids Passing Earth Today — Largest Measures 1,300 Feet, Speeding at 15,000 MPH
