📊 Circular vs Elliptical Orbits

Two-panel Studio Render comparing circular and elliptical orbits. Left: satellite on cyan circular orbit around Earth, amber gravity arrow inward, cyan velocity arrow tangential — constant speed, constant altitude. Right: satellite on amber elliptical orbit, shown slow at apogee and fast at perigee — faster when closer, slower when far.
