This interactive 3D simulation shows Earth orbiting the Sun while you adjust eccentricity, axial obliquity, and precession angle independently, visualizing how each cycle reshapes the orbital path, axis tilt, and the resulting seasonal distribution of sunlight across latitudes.
Use the sliders to set eccentricity, obliquity, and precession to any point within their real astronomical ranges, or press play to animate each cycle at its true relative period, then watch the insolation graph at 65 degrees north respond in real time.
Sliders and a play button let you independently adjust and animate eccentricity, obliquity, and axial precession to see their combined effect on Earth's orbit and seasonal sunlight distribution.
The roughly 405,000-year eccentricity cycle is so mathematically stable that geologists use it as a precise 'metronome' to date rock layers and volcanic ash beds hundreds of millions of years old, far beyond the reach of ice cores.
