The Winter Hexagon, also known as the Winter Circle, is a prominent winter asterism formed by seven stars prominent in the winter sky.
The Geminids are an annual meteor shower that usually occurs from December 7 to 17 and peaks around December 13 or 14.
The Geminids typically have a zenithal hourly rate of 75 or more meteors. The meteor shower is produced by 3200 Phaethon, an object long suspected to be a Palladian asteroid that has an unusual orbit, one that takes it closer to the Sun than any other named asteroid.

Canopus, Alpha Carinae, is the brightest star in Carina constellation and the second brightest star in the night sky.
Canopus is fainter only than Sirius. The star is a supergiant or bright giant, yellowish-white in colour, with an apparent magnitude of -0.72. It is located at a distance of 310 light years from Earth. It lies too far south and can’t be seen north of latitude 37°18’N, but it is circumpolar for observers south of latitude 37°18’S.
For northern observers, Canopus doesn’t rise very high in the sky. The name Canopus comes from the Greek name Κάνωβος (Kanôbos), first recorded in Ptolemy’s Almagest (150 AD).

Capella, also known as Alpha Aurigae or the Goat Star, is the brightest star in Auriga and the sixth brightest star in the sky.
The only stars in the northern celestial hemisphere brighter than Capella are Arcturus in Boötes constellation and Vega in Lyra. The only other star visible from northern latitudes that is brighter than Capella is Sirius in the southern constellation Canis Major.
Capella is sometimes called the Goat Star because its name is derived from the diminutive of the Latin capra, meaning “female goat,” and means “the little goat.”
