Electra: the blue star of Taurus
blue · Taurus · 17 Tau
Electra is a blue star in the constellation Taurus, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 3.70 it is visible to the naked eye under a dark sky.
Most stars in the sky are anonymous points of light. Electra 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 Electra?
Electra is a blue-white giant. 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 giant, which is what a star becomes when it exhausts the hydrogen in its core. It has swollen outward and cooled at the surface, and it is now brighter than it ever was as a young star. The Sun will do this too, in about five thousand million years.
The light you are looking at is old
Electra is about 440 light years away, so the light reaching you now set out around 1586. 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 is comfortably visible without equipment on a decent night.
What could a Electra dedication represent?
Electra 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 Taurus in the sky.”
Where can you see Electra?
It sits 24° north of the celestial equator, so it clears the horizon everywhere short of latitude 66°S, in practice, every inhabited latitude on Earth. It passes directly overhead at latitude 24°N. It stands highest at midnight in November, so November and December evenings are the best time to look. At magnitude 3.70 it is a naked-eye star only under a dark sky, binoculars make it certain.
Electra belongs to Taurus.
What does Electra mean in astrology?
The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Electra, 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, Electra stands at 29° Taurus at the J2000 epoch, and the Sun passes that degree around 19 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.
