# Tycho Brahe (@tycho-brahe)

Tycho Brahe was a Danish astronomer who created the most precise naked-eye measurements of stars and planets before the telescope. His observations made Johannes Kepler’s laws of planetary motion possible.

Tycho built observatories and instruments at an unprecedented scale under royal patronage, making systematic accuracy an institutional project.
