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 Tupi?
Tupi 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.
Tupi moves noticeably against the background sky, about 21 arcseconds a century. The constellation it belongs to will not have quite this shape in ten thousand years.
The light you are looking at is old
The light you can see from Tupi left in 1915, 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 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 Tupi?
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 37°N. It passes directly overhead at latitude 53°S. It stands highest at midnight in November, so November and December evenings are the best time to look. At magnitude 7.12 it sits below naked-eye reach; binoculars or a small telescope will find it.
Tupi belongs to Reticulum.
What does Tupi mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Tupi, 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, Tupi stands at 21° Aries at the J2000 epoch, and the Sun passes that degree around 11 April 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.
