Close Approach Data

Description

This API provides current close-approach data for all asteroids and comets within JPL’s Small-Body Database. It allows users to obtain detailed information about near-Earth objects and their proximity to our planet based on various query parameters.

What can you use it for?

Build an alert system for upcoming near-Earth passes, a visual map of asteroid flybys, or a research tool to analyze approach statistics. You can query by date range, distance, and object and get clean JSON results with distances, speeds, and uncertainties. It's free to use with no API key, but follow JPL's fair-use rules and avoid excessive automated requests. The endpoint returns a versioned signature so you can detect format changes.
