Question 1476Navigation General

The correct answer is D) Aquila. Altair is a bright star that is part of the constellation Aquila, the Eagle. This is a well-known fact in astronomy and navigation, as Altair is one of the three stars that make up the prominent Summer Triangle asterism, along with Vega and Deneb. The other answer choices are incorrect because Cygnus is the Swan constellation, Capricorn is the Sea Goat, and Hercules is the Greek hero constellation - none of which contain the star Altair.
