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. Note the flattened shape of Altair (due to rapid rotation) and the giant size of Deneb!
