"The Summer Triangle Blazes Overhead for the Labor Day Weekend"

Scheduled air date: 2002 Aug 26-Sep 01

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!
