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!
