70% to pass

If an observer is at 35°N latitude, his zenith is _______________.

A at the north celestial pole
B 35°N of the celestial equator
C 55°S of the celestial equator
D 55°N of the celestial equator
AI Explanation

The correct answer is B) 35°N of the celestial equator. The observer's zenith, which is the point directly overhead, is located at the same latitude as the observer on the Earth's surface. Since the observer is at 35°N latitude, their zenith will be 35° north of the celestial equator, which is the projection of the Earth's equator onto the celestial sphere. The other answer choices are incorrect because: A) the north celestial pole is located at 90°N, not the observer's latitude; C) 55°S of the celestial equator is the incorrect direction and distance from the observer's latitude; and D) 55°N of the celestial equator is the wrong distance from the observer's latitude.
