Only at the equator are all the stars visible over the course of the year.

Question

Quizplus · Accepted Answer

Because the Earth's axis is tilted, some stars will not be visible from certain latitudes at certain times of the year. However, at the equator, the zenith (the point directly overhead) will pass through all the stars over the course of a year, allowing for all stars to be visible. Due to the Earth's rotation and axial tilt, different stars are visible at different times of the year from different latitudes. However, at the equator, the celestial equator runs directly overhead, resulting in all stars being visible at one point or another throughout the year.
