equatorial coordinate system

The Equatorial Coordinate System is a method astronomers use to locate stars and other celestial objects in the sky. Imagine the Earth is at the center of a giant sphere. This system uses two main coordinates: 'declination', similar to latitude on Earth, which measures how far north or south an object is from the celestial equator; and 'right ascension', similar to longitude, which measures how far east an object is from a starting point called the vernal equinox. These coordinates allow observers to pinpoint the position of celestial objects accurately, regardless of their location on Earth.
