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. See more 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 formed and how Earth got its tilt. Ever since this impact, Earth has been orbiting the … See more Today, on February 22, 2024 at noon, Earth's axial tilt, or mean obliquity was 23.43627° or 23°26'10.5". Earth's mean obliquity today is … See more 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 … See more Earth's axial tilt actually oscillates between 22.1 and 24.5 degrees. The reason for this changing obliquity angle is that Earth's axis also wobbles around itself. This wobble motion is called axial precession, also known as … See more WebFeb 15, 2024 · Both were around 250 kilometers (155 miles) long and cracked the earth's crust to a depth of around 20 kilometers (12 miles).
