Orion is setting in the west with the winter constellations. Click on the tab for winter. The Big Dipper in the constellation Ursa Major is high overhead. It appears to be pouring something out. Click on the tab for the rest of the circumpolar constellations.
High in the summer sky is the Summer Triangle. The three stars in the triangle are some of the brightest stars in the night sky. Vega , the fifth brightest star in the night sky, belongs to the constellation Lyra. Below Vega is the twelfth brightest star called Altair which is part of the constellation Aquila.
The third star in the triangle is Deneb. Deneb nineteenth in brightness is part of the constellation Cygnus. Look for the cross inside the triangle.
Low in the summer sky is the constellation Scorpius. More than any other constellation the scorpion resembles its name. The brightest star is a reddish star called Antares.
Pegasus is rising in the east and bringing in the fall constellations. Click on the tab for the fall. Leo is setting in the west with the spring constellations. Click on the tab for spring. The Big Dipper in the constellation Ursa Major is in the northwest.

Draw an imaginary line through the belt stars to the lower left and you will reach the brightest star in Canis Major called Sirius.
You cannot miss it. Sirius is the brightest star in the night sky. Sirius also belongs to the Winter Triangle. These three stars are Orion's Belt, part of the constellation Orion, the Hunter. To many ancient people, the pattern of Orion looked like the figure of a human with an arrow, and the three stars were the belt around the figure's waist. Each star has its own name: Mintaka, Alnilam and Alnitak. Though they are different types of stars, distant from Earth, and distant from one another, our perspective makes them appear as an asterism a shape made of stars that aren't officially a constellation that is welcomingly familiar to anyone who enjoys stargazing.
All three stars are several times larger and brighter than our sun. Due to its bright, recognizable form, Orion's Belt has been one of the most consistently documented asterisms in the night sky throughout human history.
Orion's Belt — along with another well-known asterism, the Pleiades, are mentioned in two books of the Bible: the Book of Job and the Book of Amos. Orion is still chasing them there. In Western culture, you may sometimes hear Orion's Belt referred to as the Three Kings in a biblical reference or the three sisters. The asterism is mentioned in other cultural stories and mythologies too, from locations as varied as northwestern Mexico, Finland and India.
The Greek astronomer Ptolemy included Orion as one of the 48 original constellations in the second century. You've probably seen Orion's Belt even if you don't know anything about astronomy.
The constellation Orion is visible at night across most of the globe during the winter months in the Northern Hemisphere; during the summer months, it is in the sky during daylight hours when the sun makes it impossible to see. These seasons are reversed if you are viewing Orion from the Southern Hemisphere. Orion's Belt is located on the celestial equator an imaginary circle around the sky that is directly above Earth's equator , which means it rises high in the sky during those cold winter months with dark skies that are perfect for stargazing.
Orion rises in the east and sets in the west, starting at mid-evening midway between sundown and midnight. It rises four minutes earlier each day, or two hours earlier each month, according to EarthSky. Orion's Belt is easy to find because it is bright, and the stars in the asterism appear to be equally distant from one another based on our earthly perspective. In fact, the stars and star systems that comprise Orion's Belt are light-years apart and far distant from us between 1, and 2, light-years away from us.
As humans, our love of finding patterns and organization is what led ancient astronomers to include Orion's Belt in one of the winter sky's most clear constellations.
