Look Up! An asteroid taller than a 30-story building and another the size of a jumbo jet to pass Earth. Here's what NASA says
Synopsis
NASA reports two asteroids will closely approach Earth on August 8, 2025. Asteroid (2025 OJ1) is about 300 feet wide. Asteroid (2019 CO1) is about 200 feet wide. Both will pass millions of miles away. There is no impact risk to Earth. NASA monitors near-Earth objects for potential future threats. These flybys highlight the importance of planetary defense efforts.
Representative image NASA has issued an alert about two massive asteroids set to make close approaches to Earth on Friday, August 8, 2025. While there's no risk of impact, their impressive size, high velocity, and same-day flybys have sparked interest among scientists and space enthusiasts first asteroid, designated (2025 OJ1), measures around 300 feet (91 meters) in diameter—roughly the height of a 30-story skyscraper. According to NASA's Near-Earth Object tracking system, it will pass at a distance of 3.2 million miles (5.15 million km) from Earth—about 13 times farther than the Moon.
Despite the safe distance, astronomers are keen to observe its high-speed journey through near-Earth space. Powerful telescopes will capture its brief appearance, providing valuable data on asteroid composition, orbit, and the spotlight on the same day is (2019 CO1), an asteroid about 200 feet (61 meters) wide—similar in size to a large commercial airplane. It will pass Earth at 4.24 million miles (6.82 million km), making it slightly farther than (2025 OJ1) but still considered a close approach in astronomical smaller size doesn't make it less interesting—its speed and orbital path are closely monitored, adding to the day's rare double flyby excitement.
NASA has reassured the public that neither asteroid poses any danger to Earth. Advanced tracking confirms both will safely pass without entering our atmosphere or causing any disruption. Close approaches like these happen regularly and are part of the solar system's natural Objects (NEOs) are comets or asteroids with orbits bringing them near our planet. While most pass harmlessly, some could pose a threat in the distant future. That's why agencies like NASA continuously monitor their paths—early detection can be crucial for planetary defense, allowing time for mitigation or deflection efforts if can follow NASA's updates on these events via:NASA's Near-Earth Object Web PortalSocial media posts from the Planetary Defense Coordination OfficeLive streams during notable flybysAmateur astronomer networks also share real-time observation tips during such twin flybys of (2025 OJ1) and (2019 CO1) on August 8 serve as a reminder of the fast-moving and unpredictable environment of near-Earth space. Thanks to NASA's technology and vigilance, Earth remains well-protected from potential asteroid threats—reinforcing the importance of continued investment in planetary defense as humanity's eyes turn to the skies.
