The Right ascension of the star is about 18 h. 18 h means it is a March early-hours star and in blue sky in the morning. If 12 h RA, the star would be a March all-night star as opposite the March equinox. If 6 h RA the star would be a March late-hours star, at its high (meridian) at dusk. See more Right ascension (abbreviated RA; symbol α) is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the (hour circle of the) point in question above the … See more The Earth's axis traces a small circle (relative to its celestial equator) slowly westward about the celestial poles, completing one … See more • Celestial coordinate system • Celestial pole • Declination • Ecliptic See more Right ascension is the celestial equivalent of terrestrial longitude.
