Hru: the blue-white star of Aquila

blue-white · Aquila · σ Aql

Hru is a blue-white star, the colour of the hottest, youngest suns in the constellation Aquila, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 5.17 it is visible to the naked eye under a dark sky.

Most stars in the sky are anonymous points of light. Hru 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 Hru?

Hru is a blue-white main-sequence star. 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.

It is spending its fuel at a rate the Sun never will. Most of the bright stars in familiar constellations are this kind, which is why the night sky looks younger and hotter than the average star actually is.

A star of this class gets tens of millions of years, against the Sun's ten thousand million.

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.

Hru 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.

The light you are looking at is old

Hru is about 780 light years away, so the light reaching you now set out around 1246. You are not looking at the star as it is. You are looking at the star as it was, and there is no way to see it any other way.

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.

What could a Hru dedication represent?

Hru 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 Aquila in the sky.”

Where can you see Hru?

It sits 5° north of the celestial equator, so it clears the horizon everywhere short of latitude 85°S, in practice, every inhabited latitude on Earth. It passes directly overhead at latitude 5°N. It stands highest at midnight in July, so July and August evenings are the best time to look. At magnitude 5.17 it is a naked-eye star only under a dark sky, binoculars make it certain.

Hru belongs to Aquila.

What does Hru mean in astrology?

The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Hru, 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, Hru stands at 27° Capricorn at the J2000 epoch, and the Sun passes that degree around 16 January 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 Aquila, its stars sized by brightness and coloured by spectral type
Aquila, 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.
