AI overview
Declination is an astronomical measurement that describes how far north or south a celestial object appears in the sky, measured from an imaginary line called the celestial equator. This measurement is one of two coordinates astronomers use to pinpoint the exact location of stars and other objects in the sky, much like latitude and longitude are used to locate places on Earth.
