About Summer Solstice:

  • It is the longest day and shortest night of the year in the Northern Hemisphere.
  • During this, countries in the Northern Hemisphere are nearest to the Sun and the Sun shines overhead on the Tropic of Cancer (23.5° North).
  • At latitudes of 23.5° are the Tropics of Cancer and Capricorn, north and south of the Equator.
  • At 66.5° are the Arctic and Antarctic Circles, to the north and south.
  • Latitudes are a measure of a location’s distance from the Equator.
  • During the solstice, the Earth’s axis — around which the planet spins, completing one turn each day — is tilted in a way that the North Pole is tipped towards the sun and the South Pole is away from it.
  • Typically, this imaginary axis passes right through the middle of the Earth from top to bottom and is always tilted at 23.5 degrees with respect to the sun.
  • At the Arctic Circle, the sun never sets during the solstice.
