JPL Horizons

JPL Horizons is a powerful online tool created by NASA's Jet Propulsion Laboratory that provides detailed information about solar system objects, including planets, moons, asteroids, and comets. Users can access data like position, velocity, and orbital elements for these objects at any given time in the past or future. It's widely used by astronomers, educators, and anyone interested in space, allowing them to generate ephemeris (positional data) for scientific research, observations, and mission planning. Simply put, it helps people track and predict the movements of celestial bodies with precision.
