Astrometry

Theta and Rho

Stars are measured/studied via two primary methods: Astrometry and Photometry

Astrometry (the focus here): Measures a star’s, or another celestial object’s, position in the sky and its movement. Think of it as finding the Latitude/Longitude of a place on earth. You are finding the position of an object in the night sky.

Photometry: Measures a star’s, or another celestial object’s, flux (light output). This technique focuses on light capturing, changes, output, etc.
