vsop87
growingv3.0.0
Pure Rust VSOP87 algorithm implementation. Includes all VSOP87 algorith versions: VSOP87, VSOP87A, VSOP87B, VSOP87C, VSOP87D and VSOP87E. VSOP87 are a family of algorithms used to predict the position of planets in the solar system with great accuracy. That position can be used by astronomical software to create views of the sky, or by simulation software to know the position of the planets.
