WebDec 27, 2012 · When you think of the Earth's orientation, you'd probably imagine something like a globe, where it always rotates around an axis, called the spin axis, defined by the north and south poles. And while this … WebThe Earth’s axis rotation is at a 90-degree angle to the Sun in spring and fall, halfway between these two seasons.

WebSep 6, 2007 · The angle of inclination is used to describe the orbit data of a satellite. An angle of inclination is defined as the angle between the equatorial plane of the earth and … 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 precession of the equinoxes. It is caused by the gravitational force from the Sun, the Moon, and … See more 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 … 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 Axial precession can be described as a slow gyration of Earth's axis about another line intersecting it.
