![]() Visualizing this pole, it quickly becomes obvious that as the Northern pole is angled away from our star, the Southern pole must be angled towards it. During December, the part of the pole that extends from the Northern Hemisphere is pointing away from the sun. ![]() This pole represents the Earth's axis and is poking out into space from the Northern and Southern Hemispheres, according to an article published on NASA's Watch the Skies (opens in new tab) blog. To picture this tilt, imagine skewering the Earth on a massive pole from the Northern Hemisphere, through the center of the planet, and down to the Southern Hemisphere. Without the axial tilt, the sun would remain directly about the Equator, and everywhere on the planet would receive the same amount of light the year through.ĭuring the Winter Solstice, the North Pole is tilted at around 23.4 degrees away from the sun, meaning its rays move southward from the Equator. The axial tilt of the Earth means that as our planet journeys around the sun different areas of the planet experience varying degrees of sunlight. (Image credit: NASA/ISS Expedition 13 ) (opens in new tab)Īccording to Britannica (opens in new tab), Earth’s axis has an around 23-degree tilt and without this, not only would our planet not have a Winter Solstice, it would not have seasons at all. ![]() ![]() The planet’s axial tilt means areas of our world receive more sunlight at different times of the year. The light from the sun is not evenly distributed across the surface of the Earth. ![]()
