Hey everyone 👋 JPL Moshier Ephemeris is an MIT-licensed ephemeris engine written in C for astronomy, astrology, Panchang/almanac, and planetary calculation systems. It supports JPL kernels, Moshier, VSOP87, ELP2000, eclipse calculations, rise/set APIs, sidereal systems, houses, fixed stars, and more. The goal is to build a fully open and extensible ephemeris foundation for modern multi-language applications and libraries. Would love feedback, testing, and contributions 🙌
