During December, the Sun gains a bit of notoriety as its celestial position this month marks a change of seasons, a solstice. The word solstice describes the day, or moment, when the Sun stops its north or south apparent motion. This month, the Sun reaches the low point in its position relative to the Earth’s latitude system for those who live north of the equator. However, from the Southern Hemisphere, the Sun (with the same celestial coordinates) will be at its highest point above the northern horizon. The height that the Sun reaches in the sky depends entirely on the viewer’s latitude. In this month’s Scope on the Skies column, you’ll discover the reasons behind this celestial phenomenon.
