Overview

  • On July 26, asteroid 2025 OX—about 110 feet wide—will swing within roughly 2.81 million miles of Earth under continuous NASA observation.
  • Asteroid 2025 OW, measuring approximately 210 feet across, is set to approach at about 393,000 miles and 46,908 mph on July 28, according to JPL projections.
  • Three additional space rocks—2018 BE5, 2025 OR and 2019 CO1—are expected to pass between July 28 and early August at distances from 2.58 million to 4.24 million miles.
  • The July 18 close encounter of 2025 OS, which skimmed about 2,534 miles above Earth after its detection by ATLAS astronomers, highlighted the importance of rapid NEO tracking.
  • NASA, JPL, ATLAS and the Minor Planet Center coordinate global planetary defense efforts to catalog near-Earth objects and confirm their safe trajectories.
