WHAT:
The Independent - Asteroid 2026 QQ8 was captured by Earth’s gravity and entered a looping orbit around the planet. It is expected to complete one and a half revolutions before escaping.

Earth’s gravity has temporarily captured a tiny asteroid, which will later escape. Asteroid 2026 QQ8 poses no danger and will circle Earth before departing. Hungarian astronomer Kriztián Sárneczky first spotted the asteroid.
