WebMar 22, 2016 · Astronomers have devised such a system which is based on two quantities called Right Ascension (RA) and Declination (Dec). This celestial coordinate system of the sky is easy to understand and is rather similar to latitude and longitude used for locating landmarks here on Earth. WebRight Ascension and Declination . Declination and right ascension are coordinates resembling latitude and longitude, but instead of giving the position of location on Earth, they give a position of an object, like a star, on the sphere of the sky. Together, they make up the . equatorial coordinate system, also called the celestial coordinate ...
