Asteroid Close Approaches to Earth from 1900 to 2100

41,826 asteroid and comet flybys within 0.05 AU of Earth. The data covers close approaches over a 200-year period from 1900 to 2100. It originates from NASA's monitoring of near-Earth objects.

Use Cases

• Predict future close approach dates and distances using historical orbital parameter data.
• Cluster asteroids by velocity and miss distance to identify groups with similar threat profiles.
• Analyze temporal trends in flyby frequency using the date field over the 200-year span.
• Model the relationship between an object's estimated diameter and its relative velocity during close approach.

Strengths

• Contains 41,826 recorded flyby events.
• Covers a 200-year temporal range from 1900 to 2100.
• Focuses on close approaches within 0.05 AU of Earth.

Limitations

• Data for future events (2024-2100) are projections subject to orbital calculation uncertainties.
• No column details are provided, limiting understanding of specific features like diameter or velocity.
• The dataset may lack observational data for unobserved historical objects.
