No danger, says NASA: Airplane-sized asteroid buzzed Earth at 28,000 mph

2025 QD8, measuring 17-38 meters in diameter, passed within 218,000 kilometers of Earth at 57% of the Moon's distance with no collision threat, streamed live by Virtual Telescope Project.

The orbit of 2025 QV5 around the Sun brings it close to Earth and Venus. For most of the next century, the asteroid will pass closer to Venus more often
