About this project
Lowers the Sun below your horizon and shows Earth's shadow climbing through low orbit. The index explains that satellites make no light of their own and reflect sunlight, and that an overhead satellite at about 500 km can stay sunlit until the Sun is roughly 22 degrees below your horizon. Source
