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 Kaus Borealis?
Kaus Borealis is an orange giant. Its surface runs roughly 4,000 to 5,000°C, cool enough that the light carries a visible orange. 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.
Its colour is not the whole story. An orange star still in the steady part of its life would burn for tens of thousands of millions of years. This one is past that stage, and it is cool at the surface because it has swollen outward, not because it was born this way.
It is a giant, which is what a star becomes when it exhausts the hydrogen in its core. It has swollen outward and cooled at the surface, and it is now brighter than it ever was as a young star. The Sun will do this too, in about five thousand million years.
The light you are looking at is old
The light you can see from Kaus Borealis left in 1948, 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 does the name Kaus Borealis mean?
It bore the traditional name Kaus Borealis, which derives from the Arabic قوس qaws 'bow' and Latin boreālis 'northern'.
In the catalogue of stars in the Calendarium of Al Achsasi al Mouakket, this star was designated Rai al Naaim, which was translated into Latin as Pastor Struthionum, meaning keeper of the ostriches.
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.
Where can you see Kaus Borealis?
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 65°N. It passes directly overhead at latitude 25°S. It stands highest at midnight in June, so June and July evenings are the best time to look. At magnitude 2.81 it is an easy naked-eye star from any reasonably dark spot.
Kaus Borealis belongs to Sagittarius.
What does Kaus Borealis mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Kaus Borealis, 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, Kaus Borealis stands at 6° Capricorn at the J2000 epoch, and the Sun passes that degree around 25 December 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.
