Winter solstice to bring shortest day in northern hemisphere on Dec 22. How does it occur?

Winter Solstice is here in rrn Hemisphere bringing longest night and shortest day of year. Every year, Solstices occur twice - once in summer around June 21-22 and again during winter season on December 22-23.

Earth is tilted 23.5˚ on its axis around Sun which changes amount of sunlight being received in rrn and sourn hemispheres. As explained in im below (orbit is tilted inste of Earth), when Earth is tilted farst away from Earth, it marks Winter Solstice while it is Summer Solstice when it is tilted toward Sun at its maximum.

As a result, when it is shortest day and longest night in rrn hemisphere, it is exactly opposite in south. tably, all locations in rrn hemisphere witness days shorter than 12 hours. NASA says that days will be longer and nights shorter in rrn hemisphere until phemen is reversed starting June.

All this while, sourn hemisphere will receive direct sunlight and experience warmer temperatures. 

Interestingly, winter solstice is perfect time for stargazing given skies are clear. Currently, five planets-  Mercury, Venus, Mars, Jupiter, and Saturn - can be easily spotted in clear morning and evening skies.
