About Astronomy & Celestial Mechanics Laboratory
An astrophysics and observational astronomy laboratory. Calculate orbital velocities and Kepler periods around the Sun, Earth, Moon, Jupiter, and Mars, convert cosmic distances across AU, light-years, and parsecs with light travel times, compute black hole Schwarzschild event horizons, and evaluate telescope optical magnification and Dawes resolving limits.
Key Capabilities & Features
