Minor Planet Center

API

Free API for Minor Planet Center asteroid/comet data via Asterank

Overview

The Minor Planet Center API (hosted on Asterank) provides access to curated asteroid and comet data from the Minor Planet Center. Endpoints include asteroid search by designation, orbit parameter retrieval, and near-Earth object (NEO) listings. Responses are JSON-formatted, with fields like orbital elements, absolute magnitude, and taxonomic class. Ideal for astronomical research, educational tools, or space apps—enabling trackers for NEOs, orbit visualizations, or solar system data projects.
