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 Polis?

Polis is a blue-white supergiant. Its surface runs somewhere between 10,000 and 30,000°C, which is what gives it a blue-white cast. 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 blue-white star still in the steady part of its life would burn for tens 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 supergiant, which means it has left the stable part of its life and swollen enormously. Put it where the Sun is and its surface would swallow the inner planets. Stars this size do not fade quietly; this one will end as a supernova, and on a human timescale that could be tonight or in a million years.

Polis barely moves against the background sky, which is mostly a statement about how far away it is. For every practical purpose, including yours, it is fixed.

What does the name Polis mean?

Plato analyzes the polis in the Republic, the Greek title of which, Πολιτεία, itself derives from the word polis.

=== Modern usage === The Modern Greek word πόλη (polē) is a direct descendant of the ancient word and roughly means 'city' or an urban place.

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 Polis?

It sits 21° south of the celestial equator, so it clears the horizon everywhere short of latitude 69°N, in practice, every inhabited latitude on Earth. It passes directly overhead at latitude 21°S. It stands highest at midnight in June, so June and July evenings are the best time to look. At magnitude 3.84 it is a naked-eye star only under a dark sky, binoculars make it certain.

Polis belongs to Sagittarius.

What does Polis mean in astrology?

The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Polis, 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, Polis stands at 3° Capricorn at the J2000 epoch, and the Sun passes that degree around 22 December 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.

The constellation Sagittarius, its stars sized by brightness and coloured by spectral type
Sagittarius, drawn from catalogued positions: brighter stars are larger, and the colours follow spectral type. North is up and east is left, the sky-chart convention, so it is mirrored against a map of the ground. The joining lines are one drawing convention among several; the IAU fixes the boundaries, not the figure.
AsterNym dedications are personal commemorative records: they are not recognized by the International Astronomical Union, do not change scientific catalogue names, and do not confer ownership of a star.
