Monitor Potentially Hazardous Asteroids with NASA

The phrase “potentially hazardous asteroid” is easy to turn into an alarming headline, but it is a technical NASA classification based on orbital and size criteria. It does not mean an impact is expected. The NASA Near-Earth Objects Scraper can filter the official flag while preserving the measurements needed for responsible context.

Use a daily scheduled input

Write alert copy with a scientist or informed reviewer before automation. It should state the approach date, miss distance, estimated size range, and official classification without implying an impact. Responsible language is part of the pipeline contract, not a final editorial patch.

{"startDate":"","endDate":"","hazardousOnly":true,"maxResults":100}

Blank dates resolve to the current day. Every saved object includes estimated diameter range, close-approach date, velocity, miss distance, orbiting body, sentry status, NASA reference ID, and JPL URL. Keep the boolean field labeled “potentially hazardous” rather than shortening it to “dangerous.”

An empty dataset is a valid outcome when no feed object meets the filter. Monitoring should distinguish that state from a failed run or exhausted API quota. Use a personal NASA key for repeated schedules because the shared DEMO_KEY has lower limits.

Deduplicate a watchlist by object ID, but store each close approach separately if longitudinal analysis matters. Alert only when a new object enters the feed, a relevant approach appears, or a tracked classification changes. Link notifications to the official record and avoid converting miss distance into an impact probability. These choices create a useful scientific monitor without manufacturing urgency the source does not support.
