The Summer Triangle is still prominent in the early evening sky as Autumn begins.
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!
