Ultimately, any object can be used for celestial navigation. If it is such a distant object as a star, then it is enough to know its celestial coordinates (declination is a celestial coordinate similar to latitude, right ascension is a celestial coordinate similar to longitude). If the object is close enough to the earth (Sun, Moon), then in addition to the celestial coordinates, it is necessary to take into account the distance to these objects and their geometric dimensions.
