(A) Cygnus.
(B) Aquila.
(C) Hercules.
(D) (There is a tie.)
(E) (None of these constellations will completely set below the horizon.)
Correct answer (highlight to unhide): (A)
As read off from a starwheel, Hercules is above the south horizon as shown at 11:00 PM on September 25. Advancing time forward (while keeping the date on September 26 once the time is after midnight) indicates that Cygnus will be the last of these three constellations to set, approximately eight hours later the following day.
