Johannes Kepler

About Johannes Kepler

Johannes Kepler (1571–1630) was a pivotal German astronomer, mathematician, and astrologer who made foundational contributions to the scientific revolution. His enduring historical importance, reflected in his #141 Pantheon rank, stems primarily from his laws of planetary motion, which accurately described the orbits of planets around the Sun. These laws-elliptical orbits, equal areas in equal times, and the relationship between orbital period and semi-major axis-were derived from the meticulous observations of Tycho Brahe and provided the crucial physical framework later built upon by Isaac Newton.

Kepler's historical weight does not fully translate to modern internet attention. With 492K Wikipedia views in 2025, his attention is close to the expected level given his rank (Attention Gap of ~1x). However, this placement is juxtaposed against figures with comparable historical influence; for instance, Nicolae Ceaușescu (#393 importance) garnered 1.7M views, over three times Kepler's traffic. While his current attention level is relatively balanced against his importance, his readership is significantly lower than many more modern, but historically less impactful, figures.

His year-over-year change shows a moderate decline of -8.0% in attention, suggesting a gradual fading, though his short-term Q1 vs Q3 momentum shows a slight uptick of +2%.
