J2000 catalogue coordinates that can be independently cross-checked against astronomical databases. A planetarium app showing coordinates of date will differ slightly, because proper motion and precession move a star’s apparent position over time.
What kind of star is Aldhanab?
Aldhanab is a blue-white giant. Its surface runs somewhere between 10,000 and 30,000°C, which is what gives it a blue-white cast. Colour in a star is a temperature reading rather than a decoration: the hot ones are blue and the cool ones red, the opposite way round to a kitchen tap.
Its colour is not the whole story. A blue-white star still in the steady part of its life would burn for tens of millions of years. This one is past that stage, and it is cool at the surface because it has swollen outward, not because it was born this way.
It is a giant, which is what a star becomes when it exhausts the hydrogen in its core. It has swollen outward and cooled at the surface, and it is now brighter than it ever was as a young star. The Sun will do this too, in about five thousand million years.
Aldhanab drifts about 9.7 arcseconds a century against the stars behind it. Slow by any human measure, and still enough that the sky your distant descendants see will not be the one in your photographs.
The light you are looking at is old
The light arriving from Aldhanab tonight left in about 1815, some 211 years ago. Everything that has happened since, every person you have heard of from the last few centuries, happened while it was in transit.
That delay is the part people find hardest and like most. A star is the one thing you can give someone that was already old before either of you was born and will outlast anything else you could have chosen.
It is comfortably visible without equipment on a decent night.
What does the name Aldhanab mean?
It bore the traditional Arabic name Al Dhanab, from the Arabic الذنب al-dhanab "the tail" (of the Southern Fish)when it was still part of Piscis Austrinus with the Bayer designation κ Piscis Austrini (Kappa Piscis Austrini).
Name origin from English Wikipedia. AsterNym does not invent an etymology where none is recorded, and most stars in this catalogue have none: they carry modern names, or a catalogue designation and nothing older.
Where can you see Aldhanab?
It is easy to see from much of the Southern Hemisphere. It can also appear from lower northern latitudes, but it never rises for observers north of about latitude 53°N. It passes directly overhead at latitude 37°S. It stands highest at midnight in August, so August and September evenings are the best time to look. At magnitude 3.00 it is a naked-eye star only under a dark sky, binoculars make it certain.
Aldhanab belongs to Grus.
What does Aldhanab mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Aldhanab, and we don’t invent lore where none exists. What astrology can still read is the star’s real position, below.
Projected onto the zodiac the way fixed-star astrology reads any star, Aldhanab stands at 17° Aquarius at the J2000 epoch, and the Sun passes that degree around 5 February in the years around 2000. Fixed-star longitude shifts slowly against the tropical zodiac because of precession, about one degree every seventy-two years, so a natal conjunction must be calculated for the birth year rather than read off this J2000 value or a calendar date.
Traditional interpretations, not facts or predictions. The position and dates are computed.
