Heavens-Above

Features: Heavens-Above is a comprehensive astronomical tracking platform that provides highly accurate predictions for the visibility of the International Space Station (ISS), satellites, and other orbiting objects based on your specific geographical location. The site features an interactive sky map, detailed daily passes for various man-made satellites, information on visible planets, constellations, and comets, and an extensive database of astronomical events including meteor showers, eclipses, and asteroid flybys.

History: Created by Chris Peat in 1997, Heavens-Above was established to bridge the gap between complex orbital mechanics and the casual skywatcher. Over the decades, it has evolved from a simple satellite pass predictor into a professional-grade web resource, serving as a vital tool for amateur astronomers, educators, and space enthusiasts worldwide to bridge the connection between ground-based observation and orbiting hardware.

Use cases: Users can utilize the platform to determine the exact time, altitude, and direction to look for the ISS as it crosses the night sky from their backyard. It is also frequently used by photographers to plan long-exposure shots of satellites, by schools to teach students about orbital paths, and by astronomy hobbyists to identify "star-like" objects moving across the heavens that might be decommissioned rocket bodies or active research satellites.
