Astronomy

Astronomy is the scientific study of matter and objects  (such as stars, galaxies, planets, moons, asteroids, comets and nebulae), outside the earth's atmosphere and of their physical and chemical properties .

Sub-fields of astronomy include: Solar astronomy, Planetary science, Stellar astronomy, Galactic astronomy, Extragalactic astronomy, and Cosmology.

vCalc's Astronomy library contains equations and constants used to study these celestial objects.
