Tania Australis: the deep red star of Ursa Major
deep red · Ursa Major · μ UMa
Tania Australis is a deep red star in the constellation Ursa Major, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 3.05 it is visible to the naked eye under a dark sky.
Most stars in the sky are anonymous points of light. Tania Australis 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 Tania Australis?
Tania Australis is a red giant. Its surface runs under 4,000°C, which is cool as stars go and why the colour is unmistakably red. 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 red star still in the steady part of its life would burn for longer than the universe has yet existed. 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 arriving from Tania Australis tonight left in about 1776, some 250 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 does the name Tania Australis mean?
Tania comes from the Arabic phrase 'the Second Spring (of the Gazelle)'.
and Australis (originally australis) is Latin for 'the south side'.
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 Tania Australis dedication represent?
Tania Australis 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 Ursa Major in the sky.”
Where can you see Tania Australis?
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 49°S. It passes directly overhead at latitude 41°N. It stands highest at midnight in February, so February and March evenings are the best time to look. At magnitude 3.05 it is a naked-eye star only under a dark sky, binoculars make it certain.
Tania Australis belongs to Ursa Major.
What does Tania Australis mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Tania Australis, 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, Tania Australis stands at 21° Leo at the J2000 epoch, and the Sun passes that degree around 10 August 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.
