Which constellation does Sirius belong to?

Su Shi, a great poet, once wrote such a heroic sentence in his ci, "Look at the northwest and shoot the Sirius." In fact, Sirius mentioned in this word does not mean our Sirius. So what is Sirius and which constellation does it belong to?

Answer: Sirius belongs to Canis Canis, also called Alpha Canis, and is a first-class star. It should be noted that Sirius is only easy to see in winter or early spring.

Looking for Sirius? There are several ways:

1, Samsung

Orion is very easy to find, and Samsung, which is closely arranged between two bright stars, should be able to see it. Looking southeast along Samsung, a very conspicuous star is Sirius.

Walking along the hunter's belt to the southeast, you can see an unusually bright star shining with blue and white light. This is Sirius, the brightest star in the night sky, with an apparent magnitude of 1.5. Sirius is the alpha star of Canis Canis, which forms the outline of a dog with other brighter stars in Canis Canis. Sirius is in the dog's mouth.

2. Winter Triangle

This method is not so intuitive. To the east of Betelgeuse, there is a bright Nanhesan, which is the bright star in the upper left corner of Orion. If Nanhesan and Betelgeuse make a vertical line south, you will find him. Betelgeuse, Sirius and Nanhesan form the famous "Winter Triangle". Both of the above methods are commonly used. In fact, the easiest way to find Sirius is to look at the southern sky around 22 pm around the Spring Festival. The height of the brightest star is about 40 degrees. Which star is the brightest?
