Near-Earth Asteroid Close Approaches

Every catalogued asteroid passing within 0.05 AU of Earth in an 18-month window. Distance is shown in lunar distances (1 LD = the Earth–Moon gap, ≈384,400 km). Dot size estimates the asteroid's diameter; these are close approaches, not impacts.

Approach timeline

Each dot is one close approach · y-axis = distance in lunar distances · size ≈ diameter

The Moon sits at 1 LD (dashed line). Dots below it pass between Earth and the Moon.
