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.
A close approach is a predicted flyby, not an impact warning. Distance is shown in lunar distances for intuition, relative velocity is the encounter speed, and absolute magnitude (H) is a brightness-based proxy for size. PHA is a monitoring classification based on orbit and estimated size, not a statement of imminent danger.
Why it matters
This page is most useful for ranking flybys by how close, how fast, and how large they might be. Use the highlight cards and filters to separate routine passes from the small set of events that are especially close or worth extra context.
