What Is the Summer Solstice?

According to EarthSky, the sun rises and sets on the northernmost part of the horizon during the summer solstice. The summer solstice is not a full day; it's a particular moment where the sun ends up in the sky's northernmost area.

Live Science explains that, on equinoxes, the sun gets situated directly over the equator. However, on the summer solstice, or June's solstice, the sun rises over the northeast horizon and sets at the northwest.

People.com adds that this summer solstice signifies the official start of summer. At the same time, it marks the longest day of the year.
