Question 1574Navigation General

The correct answer is A) a solstice. The point where the Sun is at maximum declination north or south corresponds to the solstices, which occur twice a year when the Sun reaches its northernmost (summer solstice) or southernmost (winter solstice) position in the sky. At the solstices, the Sun's declination is at its maximum, either north or south of the celestial equator. The other options are incorrect because: B) Aphelion is the point in the Earth's orbit when it is farthest from the Sun, not related to the Sun's declination. C) Perihelion is the point in the Earth's orbit when it is closest to the Sun, also not related to the Sun's declination. D) An equinox occurs when the Sun's declination is 0 degrees, crossing the celestial equator, not at its maximum declination.
