  More information about Aquila

  Aquila is Latin for "the eagle". Its brightest star, Altair, has fainter
  stars on both sides, which is the quickest way to identify it: three
  stars in a short line with the middle one bright. Altair is one of the
  fastest spinning stars anyone has measured, turning once in about nine
  hours and visibly flattened by it. The figure has been an eagle for as
  long as there are records, in Babylonian lists as well as Greek ones.

  Etymology
  From        Latin
  Reading     Aquila
  Literally   the eagle

  Over 50,000 years either way the longest side of this figure changes by 1%, and the furthest
  any of its stars travels is 12.2 degrees. Deneb el Okab, Al Thalimain, HR 7377 and Altair
  drift the opposite way to the other 2, which travel together. Proper motion only: this is the
  shape changing, not the sky turning or the pole moving.
