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 Tupã?
Tupã is a yellow-white main-sequence star. Its surface runs about 6,000 to 7,500°C, a shade hotter than the Sun. 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.
A little brighter and a little shorter-lived than the Sun, and near the edge of the range where a planet could plausibly hold liquid water for long enough to matter.
A star of this class gets two to four thousand million years.
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.
Tupã drifts about 19.2 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 Tupã tonight left in about 1902, some 124 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 sits at the edge of what an unaided eye can do, so finding it is a deliberate act rather than an accident.
Where can you see Tupã?
It is a deep-southern star: easy from Australia, New Zealand, southern Africa and South America, but it never rises for observers north of about latitude 26°N. It passes directly overhead at latitude 64°S. It stands highest at midnight in March, so March and April evenings are the best time to look. At magnitude 6.99 it sits below naked-eye reach; binoculars or a small telescope will find it.
Tupã belongs to Crux.
What does Tupã mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Tupã, 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, Tupã stands at 12° Scorpio at the J2000 epoch, and the Sun passes that degree around 1 November 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.
