Winter Solstice Declination

Explanation:
Winter solstice is the Sun’s southernmost position in the sky, which corresponds to a declination of about 23°27' south of the celestial equator. Declination measures how far north or south an object appears from the celestial equator. The Earth’s axial tilt of about 23°27' means the Sun reaches -23°27' declination at the winter solstice, i.e., 23°27' south. The other values don’t fit: 23°27' north would be the northern extreme (summer solstice); 0° declination occurs at the equinoxes when the Sun is on the celestial equator; 90° south would place the Sun at the south celestial pole, which isn’t a position the Sun attains.
