The Winter Circle is an asterism appearing to be in the form of a hexagon with vertices at Rigel, Aldebaran, Capella, Pollux, Procyon, and Sirius. It is mostly upon the Northern Hemisphere's celestial sphere. On most locations on Earth (except the South Island of New Zealand and the south of Chile and Argentina and further south), this asterism is prominently in the sky from approximately December to March. There is also a pattern within the Winter Circle. It's in the southeastern part of the humongous Winter Circle, and it's called the Winter Triangle. The Winter Triangle consists of the stars Sirius, Procyon and Betelgeuse. On January 18, 2019, watch the Moon is inside the Winter Circle of Stars. https://earthsky.org/tonight/identify...
