The fixed star Tianhe marks a precise point in the zodiac at 25 degrees 16 minutes of Taurus, carrying an orb of one degree for astrological purposes. Identified as 62 Arietis, this single star lies behind the tail of the Ram within the constellation Aries. Software such as Stellarium records the same object under the designation Celestial Concave, where it registers a magnitude of 5.52.
Precise Coordinates in the Zodiac
Astrologers track Tianhe at its given ecliptic position because fixed stars maintain steady relationships to the tropical zodiac over long periods. The 25°16′ Taurus placement situates the star firmly in the late degrees of that sign, allowing practitioners to note its influence when planets or angles reach that sector. Its one-degree orb defines the range within which contacts are considered active, providing a clear boundary for chart interpretation.
Appearance and Catalog Details
At magnitude 5.52, Tianhe remains visible to the naked eye under dark skies yet requires modest optical aid in urban settings. The star’s classification as a sixth-magnitude object places it among the fainter points that still contribute to detailed stellar maps. Stellarium’s alternative label, Celestial Concave, reflects an older descriptive tradition that highlights the star’s location relative to surrounding celestial features rather than its modern catalog number.
Placement Within Aries
Although its zodiac longitude falls in Taurus, Tianhe belongs to the constellation Aries and sits immediately behind the figure’s tail. This dual identity illustrates how fixed-star work often bridges constellation outlines with tropical sign boundaries. Observers can locate the star by first identifying the Ram’s distinctive shape and then shifting attention slightly rearward along the ecliptic. The modest brightness and specific positioning of Tianhe continue to draw attention from those who combine visual astronomy with astrological study. Its coordinates and catalog references supply reliable reference points for anyone mapping the night sky or examining natal charts.
