Rosalíadecastro: the golden star of Ophiuchus
golden · Ophiuchus · HD 149143
Rosalíadecastro is a golden star, warmer-toned than our Sun in the constellation Ophiuchus, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 7.89 it is a binocular or telescope object.
Most stars in the sky are anonymous points of light. Rosalíadecastro 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 Rosalíadecastro?
Rosalíadecastro is a yellow 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.
Rosalíadecastro drifts about 8.6 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 Rosalíadecastro tonight left in about 1824, some 202 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 Rosalíadecastro dedication represent?
Rosalíadecastro 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 Ophiuchus in the sky.”
Where can you see Rosalíadecastro?
It sits 2° north of the celestial equator, so it clears the horizon everywhere short of latitude 88°S, in practice, every inhabited latitude on Earth. It passes directly overhead at latitude 2°N. It stands highest at midnight in May, so May and June evenings are the best time to look. At magnitude 7.89 it sits below naked-eye reach; binoculars or a small telescope will find it.
Rosalíadecastro belongs to Ophiuchus.
What does Rosalíadecastro mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Rosalíadecastro, 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, Rosalíadecastro stands at 6° Sagittarius at the J2000 epoch, and the Sun passes that degree around 25 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.
