TNO and Centaur Colors V9.0: Broadband Photometry for Outer Solar System Objects

NASA's TNO and Centaur Colors V9.0 supersedes all previous versions of the EAR-A-3-RDR-TNO-PHOT data series. This collection includes published broadband colors for Transneptunian Objects and centaurs, along with some comets sharing centaur-like orbits, with data published through March 2013.

Use Cases

• Classifying Transneptunian Objects based on their broadband colors
• Analyzing the surface composition of centaurs using photometric data
• Comparing the spectral properties of comets with centaur-like orbits to other outer solar system objects
• Training models to identify object families or dynamical groups from color indices

Strengths

• Supersedes all previous versions of the EAR-A-3-RDR-TNO-PHOT data series, indicating a curated update.
• Includes data from multiple published sources aggregated through March 2013.
• Broadens scope by including some comets with centaur orbits.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is current through March 2013; freshness should be verified for contemporary research.
