Near-Earth Asteroid Tracker — Live NASA NeoWs Data

About This Asteroid Tracker

AURA-AI's near-Earth asteroid tracker displays live close approach data from NASA NeoWs (Near Earth Object Web Service). Every asteroid currently tracked by NASA that is scheduled to pass within 7.5 million km of Earth is listed — with its size estimate, velocity, miss distance, and hazard classification.

Data refreshes daily and covers a rolling 7-day window. Asteroids are sourced from NASA's Center for Near Earth Object Studies (CNEOS) operated by the Jet Propulsion Laboratory (JPL).

What You Can Track

• Close approach distance — in lunar distances (LD) and kilometres
• Estimated diameter — minimum and maximum size in metres and kilometres
• Relative velocity — speed in km/s and km/h at closest approach
• Potentially Hazardous Asteroid (PHA) flag — marked if diameter >140 m and MOID <0.05 AU
• Orbital data — semi-major axis, eccentricity, inclination, first/last observation
• All historical close approaches — full record for each asteroid's past and future passes

Asteroid Size Reference

To put asteroid sizes in perspective: a 10 m asteroid is roughly the size of a bus and would mostly burn up in the atmosphere (similar to the 2013 Chelyabinsk event). A 140 m asteroid (the PHA threshold) could devastate a city. A 1 km asteroid would cause regional or global effects. The Chicxulub impactor that caused the mass extinction 66 million years ago was approximately 10–15 km wide.

No known asteroid currently poses a significant impact risk to Earth in the next 100 years, according to NASA's planetary defence programme.
