It late December, Auriga (oh-RYE-gah), the Charioteer, is almost directly
overhead at midnight. Just after sunset, it is in the east, above Orion and
to the left or north. The most prominent feature is the zero-magnitude star,
Capella. Capella's brightness is similar to Rigel, Orion's right knee, and
Vega, which is still visible in the west. The star is similar to our own
sun, but larger.
The name Capella means "she-goat," and three smaller stars nearby are called
The Kids. What does that have to do with a charioteer, you may ask? Good
question. One story has it that the charioteer was responsible for the royal
livestock, and would quite reasonably be toting goats around on his shoulder.
And Auriga couldn't be a herdsman, because there is already a herdsman, Bootes,
on the other side of the side of the night sky.
The spicier legend of Auriga completely ignores the goats. Zeus meddled with
his son's health, causing his grandson Erechtheus to be born disabled. Erectheus
then invented the chariot, a sort of proto-wheelchair, so he get around by
himself.
Orion, like the Big Dipper, is often used as a pointer to other night sky
objects. In fact, both of those constellations, as well as Taurus, point
to Auriga. Try any of these methods to confirm that your have found Auriga:
1. Follow a line away from the handle of the Big Dipper, through the two
stars on the top side of the bowl. Capella is 50 degrees away.
2. Taurus touches Auriga. The star at the end of the top horn is usually
drawn in maps as being part of both constellations, although it technically
belongs only to Taurus.
3. Capella is about 45 degrees from the middle belt star in Orion. A line
between the two will pass through the star in Taurus that abuts Auriga.
Auriga is also right on the winter Milky Way. Trace a patch from Cygnus in
the west, though Cassiopeia high in the north, and on to Auriga. The winter
Milky Way is not as brilliant as the summer Milky Way, but it gives Auriga
some star clusters. M36, M37, and M38 are all visible as hazy patches with
binoculars, and even small telescopes will bring in some nice details, especially
on M37.
