The Summer Triangle—comprised of the bright stars Vega, Altair and Deneb—is prominent in the night sky throughout the Summer, and even into Autumn. It appears high overhead around 10:00 PM this week from mid-Northern latitudes.
The three stars which make up the Summer Triangle are dramatically different in size and brightness, as well as distance from us. This shows a comparison of the sizes of these stars with our own Sun. Our solar system (including the Sun and Earth) are moving toward the nearly three million mile-wide Vega at about 43000 miles / 69000 km per hour!
