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 Deltoton?
Deltoton is a yellow main-sequence star. Its surface runs about 5,500°C, near enough the Sun's own surface temperature. 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.
This is the Sun's class. Looking at a star like this is the closest you get to seeing what our own star looks like from outside, which is a stranger thought than it first sounds.
A star of this class gets around ten thousand million years, and the Sun is halfway through its own.
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.
Deltoton is one of the fastest-moving stars in the sky. It shifts about 118 arcseconds every century, which sounds tiny and is not: over a human lifetime it visibly changes position against the stars behind it. The constellations are not fixed, they are just slow, and this one is in a hurry.
The light you are looking at is old
The light you can see from Deltoton left in 1991, 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 Deltoton mean?
Deltoton was an ancient Greek name of the constellation Triangulum, so named because the capital Greek letter delta is shaped like a triangle.
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.
Where can you see Deltoton?
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 56°S. It passes directly overhead at latitude 34°N. It stands highest at midnight in October, so October and November evenings are the best time to look. At magnitude 4.83 it is a naked-eye star only under a dark sky, binoculars make it certain.
Deltoton belongs to Triangulum.
What does Deltoton mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Deltoton, 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, Deltoton stands at 13° Taurus at the J2000 epoch, and the Sun passes that degree around 3 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.
