Civil twilight starts at 1812 zone time on 26 August, Your DR position at that time is LAT 21°06'S, LONG 14°56' W. Which statement concerning the planets available for evening sights is TRUE?
AI Explanation
The correct answer is C) Venus may be identified from Saturn and Jupiter because it is the brightest.
At the given time and location, Venus, Jupiter, and Saturn would all be visible in the evening sky. Of these, Venus is the brightest, making it the easiest to identify and distinguish from the other two planets. While sights of these planets could provide a good three-line fix (option A) or a latitude line (option D), option C is the most accurate statement regarding the relative brightness of Venus compared to Jupiter and Saturn in the evening sky.
The other options are incorrect because option B is not necessarily true (the position of Mars cannot be determined from the information provided), and option A and D, while potentially correct, do not specifically address the distinguishing characteristics of the planets as stated in option C.
