Genghe: the yellow-white star of Boötes
yellow-white · Boötes · σ Bootis
Genghe is a yellow-white star, a near cousin of our own Sun's colour in the constellation Boötes, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 4.47 it is visible to the naked eye under a dark sky.
Most stars in the sky are anonymous points of light. Genghe 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 Genghe?
Genghe is a yellow-white main-sequence star. Its surface runs about 6,000 to 7,500°C, a shade hotter than the Sun. 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.
A little brighter and a little shorter-lived than the Sun, and near the edge of the range where a planet could plausibly hold liquid water for long enough to matter.
A star of this class gets two to four thousand million years.
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.
Genghe moves noticeably against the background sky, about 23 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 Genghe left in 1974, 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 is comfortably visible without equipment on a decent night.
What could a Genghe dedication represent?
Genghe 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 Genghe?
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 60°S. It passes directly overhead at latitude 30°N. It stands highest at midnight in May, so May and June evenings are the best time to look. At magnitude 4.47 it is a naked-eye star only under a dark sky, binoculars make it certain.
Genghe belongs to Boötes.
What does Genghe mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Genghe, 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, Genghe stands at 23° Libra at the J2000 epoch, and the Sun passes that degree around 13 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.
