A Guide to the Auriga Constellation and Stars

Auriga, or "the Charioteer" is a beautiful constellation that holds captivating stories, intriguing astronomical features, and a unique position in the sky. This guide shares its myths, stars, and where to find it, providing insights that make it easy to appreciate this ancient constellation.

The Auriga constellation is located in the Northern Hemisphere and is most visible during the winter months. The name “Auriga” is Latin for “Charioteer,” symbolising a character who drives a chariot through the heavens. Auriga is often depicted in myth as a man holding the reins in one hand and a goat in the other, with two “kids” nestled nearby, adding to its distinctive shape in the sky.

As one of the 88 modern constellations recognised by the International Astronomical Union, Auriga spans a large section of the sky and contains some exceptionally bright stars and intriguing deep-sky objects.

The shape of Auriga resembles a large pentagon or irregular hexagon, easily recognisable by its bright stars. The constellation is particularly notable for its brightest star, Capella, which is one of the brightest in the entire night sky. Capella serves as a helpful guide for locating the constellation, especially when conditions for stargazing are ideal.

While we can’t measure the distance to an entire constellation, the individual stars within Auriga vary in distance. Capella, Auriga's brightest star, is about 42.9 light-years away from Earth, making it relatively close in astronomical terms. Other stars in Auriga are further out, contributing to the constellation's vast reach across our night sky.

The mythology behind Auriga is rich and varied, with connections to Greek and Roman tales. In Greek mythology, Auriga is often linked to the story of a charioteer named Erichthonius, who was an ancient king of Athens. Erichthonius was known for inventing the four-horse chariot, a skill so valued that the gods immortalised him in the stars. He is frequently depicted holding a goat, symbolised by the star Capella, along with her two kids, represented by the stars Haedi I and Haedi II.

Another myth connects Auriga to Hephaestus, the god of fire and metalworking, who was often carried in a chariot due to his lameness. This image of the charioteer in the sky adds to the constellation’s symbolic legacy of strength, innovation, and protection.

Auriga is home to a range of fascinating stars, each adding to the constellation’s charm and significance:

Auriga is home to several notable nebulae, which are regions of gas and dust where new stars are born. Among these, the Flaming Star Nebula (IC 405) stands out as a beautiful and vivid nebula. Located close to the star AE Aurigae, it offers a glowing red and blue pattern that makes it a favourite target for astrophotography.

There’s also the Tadpole Nebula (IC 410), named for its distinctive shape. The nebula’s “tadpoles” are actually dense regions of gas that appear to wriggle across the sky in long-exposure photos, creating a unique sight. The presence of these nebulae makes Auriga a prime region for those interested in observing deep-sky objects.

Auriga is best seen in the winter months, particularly from December to February, when it reaches its highest point in the northern sky. This is an excellent time to look for it, as the constellation shines brightly against the crisp winter backdrop, making it ideal for stargazing.

To locate Auriga, start by finding the well-known constellation Orion. Draw an imaginary line from Orion’s Belt up and to the left, where you’ll encounter the bright golden star, Capella. Capella is the key marker of Auriga and one of the brightest stars in the sky. Once you’ve spotted Capella, look for a pentagon shape surrounding it, which forms the main structure of the Auriga constellation. You’ll also see the "Kids," two nearby stars, adding a charming detail to its pattern.

Auriga sits close to the constellations of Taurus and Perseus, forming part of a group of constellations often visible together. The star Elnath, located on Auriga’s boundary, is shared with Taurus, linking the two constellations. 

For the clearest view of Auriga, find a dark, open space away from city lights on a crisp, moonless winter night. Once you locate Orion, follow the path to Capella, and the rest of Auriga will reveal itself, standing out beautifully among its celestial companions.
