The points in the ecliptic farthest north and south of the celestial equator are called

Solution (By Examveda Team)

For observers in the northern hemisphere, the farthest northern point above the celestial equator is the summer solstice, and the farthest southern point is the winter solstice. The word "solstice'' means "sun standing still'' because the Sun stops moving northward or southward at those points on the ecliptic.
