WISE Mission Near-Earth Object and Comet Discovery Statistics

NASA's WISE (now NEOWISE) mission data provides discovery statistics for near-Earth asteroids (NEAs), potentially hazardous asteroids (PHAs), and comets. The dataset includes daily updated counts and individual object records with orbital parameters.

Use Cases

• Analyze the discovery rate of NEAs and PHAs to assess survey efficiency over time.
• Model orbital parameters of discovered objects to study population distributions.
• Track comet discoveries and their associated orbital characteristics from the WISE mission.

Strengths

• Data is updated daily, providing near real-time discovery statistics.
• Sourced from NASA's authoritative WISE/NEOWISE mission.
• Includes a distinction between general NEAs and the more critical PHAs sub-group.

Limitations

• The specific number of rows and columns is unknown, limiting pre-analysis assessment of scale.
• Sample data and a detailed column schema are unavailable, complicating data understanding.
• The data format includes multiple options (XML, CSV, RDF, JSON) which may require format-specific parsing.
