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 Alcyone?
Alcyone 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.
The light you are looking at is old
Alcyone is about 440 light years away, so the light reaching you now set out around 1586. You are not looking at the star as it is. You are looking at the star as it was, and there is no way to see it any other way.
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 Alcyone mean?
The meaning(s) of the words is uncertain because alkyón is considered to be of pre-Greek, non-Indo-European origin.
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 Alcyone?
It sits 24° north of the celestial equator, so it clears the horizon everywhere short of latitude 66°S, in practice, every inhabited latitude on Earth. It passes directly overhead at latitude 24°N. It stands highest at midnight in November, so November and December evenings are the best time to look. At magnitude 2.87 it is an easy naked-eye star from any reasonably dark spot.
Alcyone belongs to Taurus.
What does Alcyone mean in astrology?
Brightest of the Pleiades, the weeping sisters. The tradition ties the cluster to sorrow and to vision: ambitious sight beyond the ordinary, historically read with caution around the eyes themselves.
Projected onto the zodiac the way fixed-star astrology reads any star, Alcyone stands at 29° Taurus at the J2000 epoch, and the Sun passes that degree around 20 May 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.
