📚 Understanding Asteroid Data
Distance Measurements
- • AU (Astronomical Unit): Earth-Sun distance (~150M km)
- • Close Approach: Typically within 0.2 AU
- • Very Close: Within 0.05 AU (7.5M km)
Size Estimation
- • H magnitude: Brightness measure (lower = larger)
- • H < 18: Potentially hazardous size (140m+)
- • H > 25: Small objects (few meters)
