Algorab: the blue-white star of Corvus
blue-white · Corvus · δ Crv
Algorab is a blue-white star, the colour of the hottest, youngest suns in the constellation Corvus, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 2.94 it is visible to the naked eye under a dark sky.
Most stars in the sky are anonymous points of light. Algorab 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 Algorab?
Algorab is a blue-white main-sequence star. 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 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.
The light you are looking at is old
The light you can see from Algorab left in 1939, 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 Algorab mean?
It bore the traditional name Algorab derived from Arabic الغراب al-ghuraab, meaning 'the crow'.
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 Algorab dedication represent?
Algorab 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 Corvus in the sky.”
Where can you see Algorab?
It sits 17° south of the celestial equator, so it clears the horizon everywhere short of latitude 73°N, in practice, every inhabited latitude on Earth. It passes directly overhead at latitude 17°S. It stands highest at midnight in March, so March and April evenings are the best time to look. At magnitude 2.94 it is an easy naked-eye star from any reasonably dark spot.
Algorab belongs to Corvus.
What does Algorab mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Algorab, 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, Algorab stands at 13° Libra at the J2000 epoch, and the Sun passes that degree around 2 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.
