How this service works
Upcoming asteroid close approaches to Earth from NASA JPL - object, date, miss distance in au, lunar distances and km, velocity and estimated size
Output
A JSON object containing the look-ahead window in days, the maximum distance filter in AU, total number of approaches in the window, number of items returned, a source citation, a note/caveat, and an array of close-approach records each including the asteroid object name, approach date, miss distance in AU/lunar distances/km, relative velocity, and estimated size.
Example use cases
Weekly asteroid flyby briefing
“Give me a summary of all asteroids scheduled to fly by Earth in the next 7 days, including how close they'll get and how big they are.”
Large asteroid proximity alert
“Are there any notably large asteroids coming within 0.02 AU of Earth in the next 90 days? I want to know their estimated sizes and closest approach distances.”
Science lesson on near-Earth objects
“Pull up the list of asteroid close approaches for the next 30 days from NASA JPL data — I need the object names, dates, miss distances in lunar distances and km, and their velocities.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/space/close-approaches?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, structured close-approach data sourced directly from NASA JPL CNEOS, with the ability to filter by time window and miss distance. It is ideal for agents that need fast, affordable ($0.01/call) asteroid proximity lookups without building a NASA API integration themselves.
Side effects
- Invalid days parameter (outside 1–365 range) returns an error
- Invalid max_au parameter (outside 0.001–0.5 range) returns an error
- NASA JPL upstream data unavailable causes service failure
- No close approaches in the specified window returns an empty approaches array
- Malformed query parameters result in a 400-level error
