The great goat hauler of the sky
Auriga is one weird constellation! It resembles a lopsided pentagon, but
according to Greek and Roman mythology, Auriga outlines a retired
championship chariot driver carrying a mama goat slung over one of his
shoulders, with little kid goats in the crook of his elbow. Most
constellations just don't look like what they're allegedly supposed to be.
Cultures from all over the world used these dot-to-dot or star-to-star
"pictures" as rough visual aids to share their legends or mythological stories
down through the generations. Imaginations must have been extremely
healthy back then, but Auriga takes that to the limit! There must have been
very strong libations at the party that inspired the creation of some of
these constellations.
Auriga is a hard-working constellation. He toils in our Butler evening
skies every night, although he takes much of the summer off. This time of
year, Auriga is perched high in the south-southeast sky in the early
evenings, nearly overhead. Auriga is a prominent member of the gang of
bright winter constellations I call "Orion and his gang." Look for the
lopsided pentagon just above the mighty constellation Orion the Hunter.
Three equally spaced bright stars in a perfect line denote Orion's belt.
The brightest star in Auriga is in the upper right-hand corner of the
pentagon. That's Capella, the fourth brightest star we can see in our night
sky. It's a little over 42 light-years away, with just one light-year equaling
almost six trillion miles. Capella is actually two stars orbiting each other,
separated by about a hundred million miles. There's no way we can resolve
the individual stars, even with a large telescope. Both of Capella's stars are
super large versions of our home star, the Sun. They're both close to ten
million miles in diameter, and our Sun is not even one million miles in
diameter.
According to one of the Greek legends, King Oenomaus was the ruthless
ruler of a mighty kingdom. He had a beautiful daughter, Hippodameia, who
had many suitors who wished to marry her. King Oenomaus was a classic
helicopter parent who didn't think any young man was worthy of her.
Anybody who even tried to meet her met their death! King Oenomaus
challenged every young man wooing Hippodameia to a chariot race. If the
suitor won the race, he would win the hand of the young princess. But, if
the suitor lost, he would be killed by slow torture. Since Oenomaus had the
fastest horses in the land, he routinely out-raced every young man and
disposed of them afterward.
One day though, Pelops, son of Hermes, the messenger of the gods,
came to race for the hand of Hippodameia, and he got some extra divine
help from the other gods. They were sick of the king's slaughter! Pelops
was provided a chariot that would sprout golden wings to ensure victory.
As added insurance, Pelops also paid off Oenomaus's chariot mechanic
Myrtilus to betray the king. Myrtilus replaced the "lynchpins" of the
Oenomaus's chariot wheels with copies made of wax. In return for his
betrayal, Pelops promised half of the kingdom to Myrtilus once the king
was dead.
Oenomaus started the race neck and neck with Pelops, but about
halfway to the finish line the golden wings popped out of Pelops' chariot.
The king was left in a cloud of dust. Oenomaus cracked his mighty whip,
commanding his horses to go faster and faster. That caused the wheels to
fly off, and Oenomaus was dragged off to his death!
Pelops proceeded to marry Hippodameia and live happily ever after
with the Queen of the kingdom. Myrtilus was happy for the new couple,
but he still wanted his half of the kingdom. Pelops welched on his promise
though. When Myrtilus confronted Pelops, demanding his share, Pelops
stalled him, claiming that his lawyers were drawing up all the papers and
they'd be ready in a few days. Myrtilus was satisfied with this explanation
and started walking off. Just as he did, Pelops, with his inherited godly
powers, kicked Myrtilus so hard in the derriere that he went flying into the
heavens and magically became the constellation we know today as Auriga.
No one knows exactly how the betraying chariot driver got the mama
goat and baby goats on his shoulder, but the leading theory is that
shepherds added them as they watched their flocks by night.
Again, look for Auriga the charioteer turned goat farmer nearly overhead,
above the constellation Orion. By the way, the bright star Capella marks
where the mama goat is. See if you can spot the dim triangle of stars that
make the baby goats next to Capella. Go figure!
CELESTIAL HAPPENING THIS WEEK: On Monday night you can use the
moon to easily find the distant planet Uranus. With a small telescope or
even binoculars, look for the next brightest star-like object you can see to
the right of the moon. It'll have a greenish tinge to it. Uranus is currently
over 1.8 billion miles from Earth
