In astronomy, an axisrefers to the imaginary line that an object, usually a planet, rotates around. Earth's rotational axis is an imaginary straight line that runs through the North and South Pole. In our illustrations, Earth's axis is drawn as a straight red line.
The impact around 4.5 billion years ago is described in the Giant Impact Hypothesis, which is the current prevailing theory on how the Moon was formedand how Earth got its tilt. Ever since this impact, Earth has been orbiting the Sun at a slant. This slant is the axial tilt, also called obliquity. Earth's obliquity angle is measured from the imagin...
Today, on July 23, 2024 at noon, Earth's axial tilt, or mean obliquity was 23.43608° or 23°26'09.9". Earth's mean obliquity today is about 0.00001°, or 0.04", less than 30 days ago. The Arctic and Antarctic circles today are 1.2 m (4 ft) closer to the poles, and the Tropic of Cancer and Tropic of Capricorn are equally closer to the equator than 30 ...
In a repeating cycle that lasts about 41,000 years, Earth's axial tilt oscillates between 22.1 and 24.5 degrees. This change in obliquity is caused by gravitational forces from the Sun, the Moon, and other planets.
Axial precession can be described as a slow gyration of Earth's axis about another line intersecting it. A complete wobble of Earth's axis takes around 26,000 years. It outlines the shape of a pair of cones or two spinning tops connected at the tips, which would be at the center of Earth.
Greek astronomer Hipparchus of Nicea is historically credited as the man who first proposed that Earths axis gradually shifts, though very slowly. Hipparchus made his discovery around 130 BCE, based on comparisons of astronomical observations more than a century apart.
Because Earth orbits the Sun at an angle, the solar energy reaching different parts of our planet is not constant, but varies during the course of a year. This is the reason we have different seasons and why the seasons are opposite in the Northern and Southern Hemispheres. The Sun: Our home star
Astronomical & meteorological seasons From the March equinox to the September equinox, the Northern Hemisphere tilts towards the Sun. During this time, there are more than 12 hours of daylight north of the equator. What are equinoxes and solstices? At the same time, the Southern Hemisphere tilts away from the Sun, resulting in shorter days. From th...
Different illustrators may vary which direction they incline the axis in their images. Some draw it tilted left-to-right, others right-to-left. These illustrations can both be accurate; the only difference is that the artist has chosen the opposite side of the Sun as the point-of-view.

First Quarter Moon. Waxing Gibbous Moon. Full Moon. Waning Gibbous Moon. Third Quarter Moon. Waning Crescent Moon. Primary Moon phases happen at a specific moment in time, while the time between these moments are the intermediate Moon phases. The lunar cycle lasts about 29.5 days, just under a calendar month.
