Sun Map & Planetarium - Sun Path, Sunrise & Sunset, Night Sky, Solar Position Calculator

A free interactive sun map, online planetarium and solar position calculator for any location on Earth. Track the sun's path across the sky, sunrise and sunset times, golden hour and blue hour windows, twilight zones, star and constellation positions, and yearly analemmas, visualized on a 3D globe or from a street-level view of your exact spot. It calculates also the moon position and its illumination in the sky along with the stars and constellations, so it doubles as a planetarium: a live sky map of the night sky above any place, at any date and time, out to a true-scale view of the solar system. The app gathers visualizations I initially prototyped on Mike Bostock's Observable notebooks platform (plotting-sunlight, sun-path, la-terre-est-bleue-comme-une-orange and time-zone-service).
