Aspidiske: the yellow-white star of Carina
yellow-white · Carina · ι Car
Aspidiske is a yellow-white star, a near cousin of our own Sun's colour in the constellation Carina, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 2.25 it is visible to the naked eye under a dark sky.
Most stars in the sky are anonymous points of light. Aspidiske 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 Aspidiske?
Aspidiske is a white supergiant. Its surface runs around 7,500 to 10,000°C, hot enough to look white or blue-white to the eye. 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. A white star still in the steady part of its life would burn for about a thousand million 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 supergiant, which means it has left the stable part of its life and swollen enormously. Put it where the Sun is and its surface would swallow the inner planets. Stars this size do not fade quietly; this one will end as a supernova, and on a human timescale that could be tonight or in a million years.
The light you are looking at is old
Aspidiske is about 690 light years away, so the light reaching you now set out around 1336. You are not looking at the star as it is. You are looking at the star as it was, and there is no way to see it any other way.
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 Aspidiske mean?
Turais is the Arabic تُرَيْس turais "small shield" (diminutive), while Aspidiske and Scutulum are Greek and Latin translations from ασπίδα and scūtum.
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 Aspidiske dedication represent?
Aspidiske 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 Carina in the sky.”
Where can you see Aspidiske?
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 31°N. It passes directly overhead at latitude 59°S. It stands highest at midnight in February, so February and March evenings are the best time to look. At magnitude 2.25 it is an easy naked-eye star from any reasonably dark spot.
Aspidiske belongs to Carina.
What does Aspidiske mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Aspidiske, 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, Aspidiske stands at 5° Libra at the J2000 epoch, and the Sun passes that degree around 24 September 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.
