UCAC

UCAC, or the Ultra-Precise Catalog, is a detailed database of stars that provides their precise positions, motions, and brightness. Created through careful observations, it helps astronomers accurately track stars' locations and movements over time. This information is vital for navigation, space missions, and understanding our galaxy’s structure. Think of UCAC as a highly accurate star map that enables scientists to study the universe with confidence in the positions and behaviors of the stars.
