The longest day of the year is here.
At the Summer Solstice, Earth is positioned in its orbit so that the North Pole is leaning 23.44° toward the sun. As seen from Earth, the sun is directly overhead at noon 23.44° north of the equator, at the Tropic of Cancer.
A solstice occurs twice each year, when the tilt of the Earth's axis is most inclined toward or away from the Sun, causing the Sun's apparent position in the sky to reach its northernmost or southernmost extreme. Solstice means the “sun standing still;" at the solstices the Sun stands still in declination; that is, the apparent movement of the Sun's path north or south comes to a stop before reversing direction.
