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!
