Pleione: the blue-white star of Taurus
blue-white · Taurus · 28 Tau
Pleione is a blue-white star, the colour of the hottest, youngest suns in the constellation Taurus, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 5.05 it is visible to the naked eye under a dark sky.
Most stars in the sky are anonymous points of light. Pleione is not. Some IAU-recognised names are ancient; others were adopted by the IAU only recently. Either way, the star already has a scientific identity, and a dedication attaches a human story to it.

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 Pleione?
Pleione is a blue-white star. 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.
It is spending its fuel at a rate the Sun never will. Most of the bright stars in familiar constellations are this kind, which is why the night sky looks younger and hotter than the average star actually is.
A star of this class gets tens of millions of years, against the Sun's ten thousand million.
Pleione drifts about 5.0 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 Pleione tonight left in about 1644, some 382 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 sits at the edge of what an unaided eye can do, so finding it is a deliberate act rather than an accident.
What could a Pleione dedication represent?
Pleione is especially meaningful for someone who:
- · Deserves something older than any gift shop
- · Marks a beginning, an anniversary or a promise
- · Is remembered every time you look up
- · Has a light you want recorded somewhere permanent
Dedication idea
“For the one I think of when I find Taurus in the sky.”
Where can you see Pleione?
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 5.05 it is a naked-eye star only under a dark sky, binoculars make it certain.
Pleione belongs to Taurus.
What does Pleione mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Pleione, 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, Pleione stands at 0° Gemini 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.
