Nembus: the warm orange star of Andromeda
warm orange · Andromeda · 51 And
Nembus is a warm orange giant, far along its stellar life in the constellation Andromeda, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 3.59 it is visible to the naked eye under a dark sky.
Most stars in the sky are anonymous points of light. Nembus 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 Nembus?
Nembus 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.
Nembus drifts about 12.8 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 Nembus tonight left in about 1849, some 177 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 is comfortably visible without equipment on a decent night.
What could a Nembus dedication represent?
Nembus 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 Andromeda in the sky.”
Where can you see Nembus?
It is easy to see from most of the Northern Hemisphere. It can also appear from lower southern latitudes, but it never rises for observers south of about latitude 41°S. It passes directly overhead at latitude 49°N. It stands highest at midnight in October, so October and November evenings are the best time to look. At magnitude 3.59 it is a naked-eye star only under a dark sky, binoculars make it certain.
Nembus belongs to Andromeda.
What does Nembus mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Nembus, 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, Nembus stands at 12° Taurus at the J2000 epoch, and the Sun passes that degree around 2 May 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.
