🚀 Quick Start
Star Path Viewer computes a planet or star’s positions on the celestial sphere based on input. It generates a diagram with a curved path representing the apparent motion projected onto the observer’s local horizontal coordinate system. A table of the rising/setting/transit/twilight times and star positions will also be appended.
