Alnasl: the warm orange star of Sagittarius

warm orange · Sagittarius · γ2 Sgr

Alnasl is a warm orange giant, far along its stellar life in the constellation Sagittarius, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 2.98 it is visible to the naked eye under a dark sky.

Most stars in the sky are anonymous points of light. Alnasl 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 Alnasl?

Alnasl 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.

Alnasl drifts about 19.0 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 you can see from Alnasl left in 1929, 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 Alnasl mean?

Alnasl is derived from the Arabic النصل al-naşl and Nushaba is derived from the Arabic Zujj al-Nashshaba, both meaning "arrowhead".

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 Alnasl dedication represent?

Alnasl 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 Sagittarius in the sky.”

Where can you see Alnasl?

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 60°N. It passes directly overhead at latitude 30°S. It stands highest at midnight in June, so June and July evenings are the best time to look. At magnitude 2.98 it is an easy naked-eye star from any reasonably dark spot.

Alnasl belongs to Sagittarius.

What does Alnasl mean in astrology?

The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Alnasl, 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, Alnasl stands at 1° Capricorn at the J2000 epoch, and the Sun passes that degree around 20 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.

The constellation Sagittarius, its stars sized by brightness and coloured by spectral type
Sagittarius, drawn from catalogued positions: brighter stars are larger, and the colours follow spectral type. North is up and east is left, the sky-chart convention, so it is mirrored against a map of the ground. The joining lines are one drawing convention among several; the IAU fixes the boundaries, not the figure.
AsterNym dedications are personal commemorative records: they are not recognized by the International Astronomical Union, do not change scientific catalogue names, and do not confer ownership of a star.
