About Asteroid Data
Data Source
Asteroid orbital elements from the Minor Planet Center (MPC) MPCORB database. Positions and magnitudes calculated using Skyfield astronomical library.
Magnitude Calculation
Visual magnitudes calculated using the standard asteroid formula: V = H + 5*log₁₀(r*Δ) - 2.5*log₁₀((1-G)*Φ₁ + G*Φ₂) where H is absolute magnitude and G is the phase parameter.
Visibility Information
Rise, transit, and set times are calculated for your specific location. Altitude shows current height above horizon (negative = below horizon).
Update Frequency
Positions are calculated in real-time and cached for 1 hour. Orbital elements are updated daily from MPC.
