What is Summer solstice?

About Summer solstice:

• In Latin, "Solstice" means "sun stands still".
• It is an annual astronomical phenomenon that brings the longest day of the year.
• On the summer solstice, the Northern Hemisphere is tilted toward the sun, receiving the full glare of the sun's rays.
• During the solstice, the Earth’s axis — around which the planet spins, 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.
• What happens during the solstice?
  • This day sees the Earth receiving a greater amount of energy from the Sun.
  • Each year, the summer solstice in the Northern Hemisphere falls on one of two days: June 20 or June 21.In the Southern Hemisphere, the summer solstice happens on Dec. 21 or Dec. 22.
  • The date varies because the Gregorian calendar has 365 days, with an extra leap day added in February every four years. 
  • The amount of light received by a specific area in the Northern Hemisphere during the summer solstice depends on the latitudinal location of the place.
  • The further north one moves from the equator, the more light one receives during the summer solstice. At the Arctic Circle, the sun does not set during the solstice.
