An open, community-maintained database of all discovered extrasolar planets, stored as human-readable XML files in a git repository. New planets are typically added within 24 hours of announcement, and data can be queried easily from Python.

Use cases

• get a list of all discovered exoplanets with mass and radius
• find circumbinary planets or planets in binary star systems
• download exoplanet data for scientific research or a paper
• query planetary system distances and planet counts with Python
• build plots or histograms of exoplanet properties
• find habitable zone planets for outreach or education

When to choose

• you need an open, freely licensed (MIT) exoplanet dataset with full version history
• you want community-curated data updated quickly after discoveries
• you prefer human-readable XML files you can parse without special libraries

When to avoid

• you need a REST API or SQL database interface rather than raw XML files
• you require guaranteed peer-reviewed data quality for every entry
• you need comma/tab-separated tables without extra processing (use the oec_tables repository instead)
