# Astronomy

Astronomy calculations apply physics to planets, stars and space: Kepler's third law links an orbit's period to its size, and surface gravity on the Moon is about 1.62 m/s², roughly one sixth of Earth's 9.81 m/s². Escape velocity, light-year and parsec distances, star brightness and telescope magnification are other common results.
