Antares: the heart of the Scorpion, rival of Mars
deep red · Scorpius · α Sco
Antares is the red heart of Scorpius, a supergiant so distinctly red that the Greeks named it “rival of Ares,” the equal of Mars, because the planet and the star burn the same colour when they pass.
A star named for holding its own against a god of war is a dedication for someone who never backs down, or for a love that sits, unmistakably, at the heart of things.

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 Antares?
Antares is a red supergiant. Its surface runs under 4,000°C, which is cool as stars go and why the colour is unmistakably red. 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 red star still in the steady part of its life would burn for longer than the universe has yet existed. 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.
The light you are looking at is old
Antares is about 550 light years away, so the light reaching you now set out around 1476. 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 also one of the brighter stars in the sky, which is why it carries a proper name at all rather than a catalogue number.
What does the name Antares mean?
Antares is Greek: anti-Ares, “rival of Mars.” When the red planet passes through Scorpius, the two face each other, and the star does not blink.
What could a Antares dedication represent?
Antares is especially meaningful for someone who:
- · Is the heart of your story
- · Holds their ground against anyone
- · Burns red · passionate, unmistakable, alive
- · Would rival a planet rather than dim
Dedication idea
“For the heart I would know in any sky.”
Where can you see Antares?
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 64°N. It passes directly overhead at latitude 26°S. It stands highest at midnight in May, so May and June evenings are the best time to look. At magnitude 0.96 it is bright enough to hold its own over city lights.
Antares belongs to Scorpius, where it is the brightest star.
What does Antares mean in astrology?
The "heart of the Scorpion", a Persian royal star, watcher of the west, and the classical rival of Mars. Its name means "like Ares". The tradition reads it as intensity itself: courage, obsession, all-or-nothing turns of fortune.
Projected onto the zodiac the way fixed-star astrology reads any star, Antares stands at 9° Sagittarius at the J2000 epoch, and the Sun passes that degree around 28 November 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.
