Question

BlackTom AI · Accepted Answer

The question asks about a feature on the celestial sphere that lies halfway between the celestial poles.
Option 1: ecliptic. The ecliptic is the apparent path of the Sun across the sky over the year, lying close to the zodiac. It is not defined as halfway between the poles, so this choice is incorrect.
Option 2: horizon. The horizon is the circle where the sky seems to meet the Earth from a given observation point; it depends on the observer's location and has no fixed relation to the celestial poles. This makes it an unsuitable answer.
Option 3: celestial equator. The celestial equator is the projection of Earth's equator onto the celestial sphere, and by construction it lies exactly midway between the celestial poles. This is exactly the description given in the question, so this option is correct.
Option 4: zenith. The zenith is the point directly overhead from the observer's position. It does not relate to the polar positions or to a midway location between the poles, so this is not correct.
Option 5: meridian. The meridian is a great circle passing north–south through the observer's zenith and nadir; it is a directional reference on the sky but not the halfway line between the poles. Therefore this choice is incorrect.
