Question 1654Navigation General70% to pass
If the right ascension of a body is 9 hours, it also _______________.
AI Explanation
The correct answer is A) is 135°.
Right ascension is measured in hours, minutes, and seconds, with 1 hour corresponding to 15 degrees. Since the right ascension of the body is 9 hours, this means its right ascension is 135° (9 hours x 15 degrees/hour = 135 degrees).
The other options are incorrect because:
B) corresponds to an SHA of 45° is incorrect, as the SHA (sidereal hour angle) would be 135°, not 45°.
C) means the GP (geographical position) is in the western hemisphere is incorrect, as a right ascension of 9 hours could correspond to a position in either the eastern or western hemisphere.
