Every asteroid known to be on course to pass closer than 2 lunar distances (≈ 769,000 km) from Earth between now and 2100 — assembled live from NASA/JPL close-approach data. Each one has a profile page: its orbit, every catalogued Earth encounter, its size against things you know, and — for the famous ones — the full story. None of these will hit Earth.
Data: NASA/JPL CNEOS Close-Approach Data API and Small-Body Database. Sizes without a measured diameter are estimated from absolute magnitude (H) assuming a typical albedo — treat them as a factor-of-two range, not a precise figure. Hero images are procedural artist's impressions unless labelled as real radar/telescope imagery. © 2026 Mike DiCarlo.
