Answer:
1. The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (usually 21 or 22 December) and in the Southern Hemisphere, this is the June solstice (usually 20 or 21 June).
2. The Sun lies directly over 23 1/2o south. Occurring during the astrological sign of Capricorn, 23 1/2o south latitude is called the Tropic of Capricorn. Continuing to March 21st (i.e. spring equinox) the Earth has positioned itself similar to that which occurs in September, only on the other side of the Sun.
3. June 21
The latitude of 23 ½ degrees north is known as the Tropic of Cancer, and it is the northern boundary of the tropics. Question: On June 21, the subsolar point is at about 23 1/2 degrees north.
4. In 2020, the Sun will cross the celestial equator from north to south on September 22, at 13:30 UTC. Because of time zone differences, the equinox will take place on September 23, 2020 at locations that are at least 10:30 hours ahead of UTC.
5. December 21st was the Winter Solstice in the northern hemisphere. That's the day when Earth's north pole was pointed completely away from the Sun. If you lived north of the Arctic Circle, like Santa Claus, you would have experienced 24 hours of darkness. It was the day Sun never rose.
6. The farthest south that the sun's rays shine directly is latitude 23 ½ degrees south, the Tropic of Capricorn. This is the southern boundary of the tropics. On this day, the area north of the Arctic Circle gets no sunlight, and the area south of the Antarctic Circle gets 24 hours of light.
7. Tropic of Capricorn, 23 1/2 degrees S. Tropic of Cancer, 23 1/2 degrees N. Arctic Circle, 66 1/2 degrees N. Antarctic Circle, 66 1/2 degrees S. North Pole, 90 ...
8. Tropic of Capricorn: 23.5 degrees south of equator. ... at midday on December 21 is 90-36-23.5 = 30.5 degrees; on March 21
9. equator
The equator is an imaginary line drawn right around Earth's middle, like a belt. It divides Earth into the Northern Hemisphere and the Southern Hemisphere. Another imaginary line drawn straight through Earth connecting the North Pole to the South Pole is Earth's axis of rotation.
10. A day is the amount of time it takes a planet to finish one rotation on its axis. It takes Earth approximately 365 days and 6 hours to orbit the Sun. It takes Earth approximately 24 hours — 1 day — to rotate on its axis. So, our year is not an exact number of days.
