BSL Astronomy Glossary - winter triangle - definition

Definition: In the night sky, during the winter months, the Winter Triangle is clearly visible from the northern hemisphere. It is made up of three bright stars each of which belongs to a different constellation. The first star, Procyon, belongs to the constellation of the small dog, Canis Minor; the second star is Betelgeuse in the constellation of Orion and the third star is Sirius, in the constellation of Canis Major, the large dog. When the illustrations are removed from the video clip, it is easy to identify the three bright stars that make up the Winter Triangle.
