Earth's Axial Tilt and Seasonal Changes: A Celestial Journey – AI Generated Video | Hailuo AI

Generate & Play Hailuo AI video：The Earth tilts at an angle of about 23.5 degrees relative to the plane of its orbit around the Sun. This means that throughout the year, different parts of the Earth will receive different amounts of sunlight. Earth's Orbit: The Earth orbits the Sun on an elliptical path, which also affects the distribution of sunlight. Seasonal Phenomena Summer: In the Northern Hemisphere, days are longer than nights. For example, on the Summer Solstice (around June 21st), the Northern Hemisphere tilts towards the Sun, leading to the longest day of the year. In the Southern Hemisphere, the opposite occurs, with days shorter than nights. Winter: On the Winter Solstice (around December 21st), the Northern Hemisphere tilts away from the Sun, resulting in the shortest day and longest night of the year. While the Southern Hemisphere experiences summer with days longer than nights. Spring and Autumn: At the times of the Vernal Equinox (around March 20th-21st) and the Autumnal Equinox (around September 22nd-23rd), day and night are approximately equal everywhere on Earth. Example details: Hanoi (Northern Hemisphere): Mid-summer (around June): Days are about 13-14 hours long, nights are about 10-11 hours. Mid-winter (around December): Days are about 10-11 hours long, nights are about 13-14 hours. Sydney (Southern Hemisphere): Mid-summer (around December): Days are about 14-15 hours long, nights are about 9-10 hours. Mid-winter (around June): Days are shorter, about 9-10 hours, nights are about 14-15 hours.
