Quadrans: the golden star of Boötes
golden · Boötes · 44 Boo A
Quadrans is a golden star, warmer-toned than our Sun in the constellation Boötes, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 5.14 it is visible to the naked eye under a dark sky.
Most stars in the sky are anonymous points of light. Quadrans 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 Quadrans?
Quadrans is a yellow main-sequence star. Its surface runs about 5,500°C, near enough the Sun's own surface temperature. 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.
This is the Sun's class. Looking at a star like this is the closest you get to seeing what our own star looks like from outside, which is a stranger thought than it first sounds.
A star of this class gets around ten thousand million years, and the Sun is halfway through its own.
It is a main-sequence star, which despite the word dwarf simply means it is in the long stable middle of its life, fusing hydrogen in its core exactly as the Sun is doing now.
Quadrans moves noticeably against the background sky, about 44 arcseconds a century. The constellation it belongs to will not have quite this shape in ten thousand years.
The light you are looking at is old
The light you can see from Quadrans left in 1985, which puts it roughly a lifetime ago. Nobody has invented anything since then that the light knows about; it has simply been travelling.
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 does the name Quadrans mean?
The Greek word for the quadrans was κοδράντης (kodrantes), which was translated in the King James Version of the Bible as "farthing" (which itself means fourth- + -ing).
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.
What could a Quadrans dedication represent?
Quadrans 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 Boötes in the sky.”
Where can you see Quadrans?
It is easy to see from most of the Northern Hemisphere. It can also appear from lower southern latitudes, but it never rises for observers south of about latitude 42°S. It passes directly overhead at latitude 48°N. It stands highest at midnight in May, so May and June evenings are the best time to look. At magnitude 5.14 it is a naked-eye star only under a dark sky, binoculars make it certain.
Quadrans belongs to Boötes.
What does Quadrans mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Quadrans, 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, Quadrans stands at 17° Libra at the J2000 epoch, and the Sun passes that degree around 7 October 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.
