Overview

• NASA’s JPL forecasts 2025 QD8 will pass about 136,000 miles (≈218,000 km) from Earth at roughly 10:57 a.m. ET, or about 57% of the average Earth–Moon distance.
• The object’s diameter is estimated at 17–38 meters based on reflected-light observations, and it will be moving at roughly 28,000 mph relative to Earth.
• ESA calculations indicate this will be the asteroid’s closest recorded approach for roughly a century, with future encounters expected at larger distances.
• The Virtual Telescope Project is livestreaming the flyby using robotic instruments, while observatories conduct follow-up measurements to reduce orbital and size uncertainties.
• A separate, smaller asteroid designated 2025 QV5 will pass at about 500,000 miles, with no threat expected, and is a target for NASA’s Goldstone radar imaging.
