[Starry Sky Master Newsletter vol.4] Winter Constellations: Canis Major
This week too, the starry sky master will bring you starry sky knowledge that you'll want to talk about tomorrow.
This time, we will be talking about the winter constellation Canis Major, which is one of the Winter Triangle and is home to Sirius, the brightest star in the constellation.
[Canis Major]
Sirius, the brightest star in the sky
The landmark of Canis Major is its brightest star, Sirius. It is also the brightest star among the 7,000 or so stars in the entire sky. To find Sirius in the starry sky, you can find the neighboring constellation Orion, but it might also be a good idea to look at the southern winter sky and look for the brightest star.
Additionally, the triangle formed by Sirius in Canis Major, Betelgeuse in Orion, which we covered last time, and Procyon in Canis Minor, is called the Winter Triangle.
The two dogs that accompanied Orion the Hunter
Orion, a hero in Greek mythology, was known as a master hunter and always had two hounds with him. One day, during a hunt, he noticed that he had prey. However, the prey was on the other side of the Milky Way, and he had to cross the river to get it.
One of Orion's hounds was a canine and the other was still a puppy. Orion took only the canine and crossed the river. So the Milky Way flows between Orion, the canine and the puppy.
It is said that the puppy gazes at the two of them with a sad look on its face.
In the winter, when the beautiful Canis Major shines brilliantly, why not gaze at the night sky at Grand Chariot Big Dipper 135° while thinking about the mythology of the constellation? We look forward to seeing you there.
