Leepwal: the blue-white star of Centaurus
blue-white · Centaurus · ζ Cen
Leepwal is a blue-white star, the colour of the hottest, youngest suns in the constellation Centaurus, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 2.55 it is visible to the naked eye under a dark sky.
Most stars in the sky are anonymous points of light. Leepwal 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.

What kind of star is Leepwal?
Leepwal is a blue-white subgiant. 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.
It is a subgiant, caught in the short crossing between an ordinary life and a giant one. Its core has run out of hydrogen but its outer layers have not finished expanding, and astronomically this stage passes quickly.
Leepwal drifts about 7.3 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 Leepwal 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 is comfortably visible without equipment on a decent night.
What could a Leepwal dedication represent?
Leepwal 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 Centaurus in the sky.”
Where can you see Leepwal?
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 43°N. It passes directly overhead at latitude 47°S. It stands highest at midnight in April, so April and May evenings are the best time to look. At magnitude 2.55 it is an easy naked-eye star from any reasonably dark spot.
Leepwal belongs to Centaurus.
What does Leepwal mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Leepwal, 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, Leepwal stands at 14° Scorpio at the J2000 epoch, and the Sun passes that degree around 3 November 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.
