Near-Earth objects, in perspective

Near-Earth is an orbital classification

The catalog preserves JPL’s NEO flag and official orbit-class code. Crossing the Earth’s orbital region does not mean that two objects occupy the same place at the same time.

Hazard classification is not an impact prediction

A potentially hazardous classification helps prioritize monitoring. It does not mean a collision is predicted. This explorer does not turn orbital intersection distance (MOID) into a dated encounter or assign an impact probability from an illustrative path.

Inspect an actual encounter

Use the Events panel to select a JPL CAD close approach. Read the nominal distance, relative velocity and available three-sigma ranges, then load the selected object’s JPL vectors to frame the encounter at the published date.

Sources & scientific accuracy

NASA/JPL SBDB supplies catalog identities and orbital elements, Horizons supplies dated trajectories, and CAD supplies close-approach records. An encounter is a calculated passage, not an impact warning. Source dates, orbit solutions and available uncertainty fields are shown in the explorer.

Display radii, generic shapes and comet activity are illustrative. Read Tuduni’s time and accuracy guide or view data sources and credits.
