Near-Earth Objects
Near-Earth objects on TerraPulse are organized into the neo CelestialObjectDex — one
slot per close approach. Asteroids and comets whose orbits bring them near Earth are
tracked by telescope; each slot records a pass that was actually measured, with the miss
distance and speed nailed down by observation. No estimates, no forecasts.

Provenance
Every approach traces to NASA/JPL CNEOS, the Center for Near-Earth Object Studies at the Jet Propulsion Laboratory, and its close-approach database. CNEOS computes each object’s trajectory from telescope observations and logs every pass within about 0.05 astronomical units of Earth. Those logged passes are the slots in this dex.
What’s in a record
Each approach slot carries:
- Object — the asteroid or comet designation
- Time — the close-approach date and time, UTC
- Miss distance — how close it came, in astronomical units and lunar distances
- Relative velocity — its speed past Earth, in km/s
- Estimated size — the diameter range inferred from brightness
