Kepler K2 Data Search Catalog: Exoplanet Survey Observations

Launched in 2009, the Kepler Mission surveyed a region of our galaxy to determine the fraction of stars with planets and measure exoplanet size distribution. The K2 mission, continuing from 2013 onward, provides the main catalog for all K2 data via this service from the National Aeronautics and Space Administration. The catalog was last updated on 2026-03-13.

Use Cases

• Identify candidate exoplanets based on transit photometry data.
• Analyze stellar light curves for variability and activity.
• Conduct statistical studies on exoplanet size and orbital distribution.
• Train machine learning models for automated transit signal detection.

Strengths

• Data originates from the authoritative NASA Kepler and K2 missions.
• Catalog provides the main search service for all K2 mission data.
• Mission has a long operational timeline, from primary mission completion in 2013 to ongoing K2 observations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in a BIN format, which may require specialized tools for access and analysis.
