Glyph for Okyrhoe


Okyrhoe (also spelled Ocyrhoe) (52872) was discovered on September 19, 1998 at 24 Pisces 35. This is quite significant, because it was conjunct the fixed star 51 Pegasi at that time.

Astronomers have discovered several stars that have one or more planets of their own by we know ours is not the only solar system in the universe. But the very first sun-like star (similar to our own Sun) to be discovered with a planet was 51 Pegasi, which opened up a whole new field of astronomical research, and verified that our solar system is not unique. (Before its discovery, the only planets convincingly observed were forbidding worlds orbiting pulsars.) So it is a pretty important star...and makes Okyrhoe's discovery all the more significant.

The planet around this star has been given an official name, Bellerophon. I will talk more of this shortly. can see this star in the night sky with the naked eye, if you know where to look. It's that bright.

When Okyrhoe is closest to the Sun (perihelion), it almost reaches Jupiter's orbit, while when furthest from the Sun (aphelion), it goes well out beyond the orbit of Saturn. Thus, it could be viewed as a bridge between Jupiter and Saturn.

It has the shortest orbital cycle of any Centaur, only 24.3 years. It's eccentricity is 0.309, with an inclination of 15.6.



In Greek, Okyrhoe means "swift running" or "fast flowing." Her father was Chiron, wisest of all Centaurs, while her mother was the water nymph Chariklo.

Okyrhoe had the gift of prophecy. For example: Chiron was entrusted by Apollo to care for a baby named Aesculapius, and so brought the child to his cave. As Chiron arrived, Okyrhoe came out to meet him, and...upon seeing the child...burst forth into a prophecy:

Grow strong, dear boy
Healer of all the world.
Often to you
Men shall owe health and life,
and yours shall be
The right to win again departed souls,
And, though you dare this once in heaven's despite,
Jove's bolt will thwart that gift a second time.
You, now divine, shall be a lifeless corpse,
And from a corpse become divine again,
And twice you shall renew your destiny.
In this, she predicted that the baby would grow up to be one of the greatest healers ever known, able to bring even the dead back to life. But in doing this, he would eventually anger the gods, who would strike him down, and yet, he would be reborn as a god himself, taking his place in the pantheon.

Okyrhoe had a gift, it is true. But she was also entrusted not to reveal some things the gods wanted kept hidden, and when she broke the rules, she suffered for it.

One day, she predicted that her father, an immortal, would be granted death by the other gods because the pain of a serpent's venom would torment him. But she only was able to speak part of the prophecy.

"And from her deepest heart Ocyrhoe sighed,
and ears ran down her cheeks;
she said: "The Fates have checked my speech.
I am allowed to say no more;
they will not let me use my voice.
What good was there in having learned this art,
if now it only draws the wrath of gods against me?
Would I not be better off
Without the power to predict the course of days to come?
I can already sense that they are stripping all my human semblance."
(Ovid's Metamorphoses)
With this, Apollo turned her into a mare as punishment for revealing the plans of the gods to humankind.


The myth goes that Bellerophon wanted to ride the winged horse Pegasus, and sought Athena's aid. He spent the night in her temple. offered her many gifts, and she repaid him with a special golden bridal and instructions on where to find Pegasus. Bellerophon succeeded, and soon was off on Pegasus doing marvelous deeds, such as killing the dreaded monster, the Chimera.

Bellerophon had one success after another, getting braver and more aggressive with each, until one day he decided to ride up to Mount Olympus to visit the gods themselves! Zeus, angry with Bellerophon's arrogant attempt to scale Mount Olympus' heights, sent a gadfly to punish the mortal for daring to ascend to the home of gods. The fly stung Pegasus, and so startled the horse that he suddenly reared, and Bellerophon was hurled off of his back. He plummeted to the ground.

Athena spared his life by causing him to land on soft ground. But for the rest of his life, Bellerophon traveled, lonely and crippled, in search of Pegasus, but never found him again. No man would help him because of his offense to the gods.

Bellerophon provides a lesson in the proper relationship between a mortal hero and the gods. When he was young he honored the gods and won their favor but, then his pride got the better of him and led to his downfall.


The Sabian Symbol for the degree of Okyrhoe's discovery (and the star 51 Pegasi) reads, "The purging of the priesthood."

51 Pegasi is located in the shoulder/wing of the constellation Pegasus (The Flying Horse). In Greek mythology, Pegasus is the winged horse that was fathered by Poseidon with Medusa. When her head was cut of by the Greek hero Perseus, the horse sprang forth from her pregnant body. Pegasus represents the warrior spirit, bravery, courage, heroic deeds, creative inspiration, universal love. The desire for acquiring knowledge and the ability to present it in dramatic and fascinating ways.

Okyrhoe's cycle is only a few years shorter than that of Saturn's, which produces a very interesting result. I searched for aspects between these two bodies between 1800-2006, and in all that time there was only one exact conjunction: August 24, 1863, at 3 Libra 59. And yet, in that same time interval, the two bodies were exactly square 40 times, and opposition 19 times.

It is reminiscent of Chiron, which only had one conjunction with Chiron in the 20th Century. But in Okyrhoe's case, there was only one conjunction in over 2 centuries.

While I was reading up on the history of the year 1863, I noticed that the Red Cross was founded that year on October 29. While there is no close Okyrhoe conjunction to Saturn at that time, the chart for the Red Cross has Okyrhoe closely conjunct Mercury.

And Charles Ringling, founder of the Ringling Brothers Circus, was born December 2, 1863, with a very close Venus Okyrhoe conjunction.

On Amable's blog, Transneptunian Astrology, there are some interesting observations about Okyrhoe: "Okyrhoe was a female centaur that was transformed into a mare: Okyrhoe allows speed action like Marty Mc Fly at the end of the movie "Back to the Future" (1985), or like Anakin at the podracing tournament (Star Wars Episode I: The Phantom Menace, 1999), like the final movement of Mulan at the end of the movie (Disney, 1998), or the movie "The Peacemaker" (1997). The danger of Okyrhoe is to make a false move because of its strong ability for anticipation."

Mark Andrew Holmes has written that Okyrhoe "seems to indicate being criticized or attacked, being able to cope with attacks or unpopularity, ability to stand up for one's beliefs or principles." Check out his Okyhroe page:
