Get Satellite Orbital Elements by NORAD ID

Retrieve the current Two-Line Element (TLE) orbital data for a specific satellite using its NORAD catalog number. Returns the full GP (General Perturbations) element set: epoch, inclination, RAAN, eccentricity, argument of perigee, mean anomaly, mean motion (revolutions/day), B* drag coefficient, and computed orbital period in minutes. Data is sourced from the US Space Force 18th Space Control Squadron via CelesTrak. Useful for orbital mechanics calculations, satellite pass predictions, and tracking any of the 27,000+ catalogued space objects. Popular NORAD IDs: 25544 (ISS), 20580 (Hubble), 33591 (NOAA-18).
