Upcoming asteroid and comet flybys near Earth
A close approach is a predicted flyby where an object passes near Earth. This view focuses on objects within 0.05 AU (about 7.5 million km), sourced from NASA JPL CNEOS.
Distances are shown in Lunar Distances (LD), where 1 LD = 384,400 km. Relative velocity is the encounter speed with respect to Earth, and the H value (absolute magnitude) is a proxy for size and brightness. The PHA filter highlights “potentially hazardous asteroids” based on NASA’s standard criteria; orbital solutions can improve over time, so encounter details may be revised.
