Question

Where should be your location on Earth to see Vega practically crosses your zenith?

a. Jacksonville, Florida (30º 22'N).
b. Equator.
c. Sacramento, California (38º 35'N).
d. Antarctica below 61º S

Answer 1

The location on Earth where Vega practically crosses your zenith is Sacramento, California (38º 35'N).

Step-by-step explanation:

The location on Earth where Vega practically crosses your zenith would be (c) Sacramento, California (38º 35'N). The north celestial pole, which is 90° from the celestial equator, would be at an angle equal to the observer's latitude. Therefore, for an observer at 38° N latitude, the north celestial pole would be 38° above the northern horizon. This means that Vega, which is located near the north celestial pole, would appear very close to the observer's zenith in Sacramento, California.
