🧪 Planetarium Field of View and Limiting Magnitude

This interactive simulation allows you to explore the complex mechanics of orbital motion around a star. By adjusting parameters like eccentricity and inclination, you can observe how planetary orbits behave in a realistic simulated environment. The deep-space star field now redraws live as you change the field-of-view and limiting-magnitude sliders, showing more or fewer, brighter or fainter stars.
