Earth's orbital plane is known as the ecliptic plane, and Earth's tilt is known to astronomers as the obliquity of the ecliptic, being the angle between the ecliptic and the celestial equator on the celestial sphere. [6] It is denoted by the Greek letter Epsilon ε. Earth currently has an axial tilt of about 23.44°. [7]
To show a location about Earth using the ECI system, Cartesian coordinates are used. The x–y plane coincides with the equatorial plane of Earth. The x-axis is permanently fixed in a direction relative to the celestial sphere, which does not rotate as Earth does.
In addition to the steady progressive motion (resulting in a full circle in about 25,700 years) the Sun and Moon also cause small periodic variations, due to their changing positions. These oscillations, in both precessional speed and axial tilt, are known as the nutation. The most important term has a period of 18.6 years and an amplitude of 9 ...
The tilt is determined by a differential equation for u = cos(θ) of the form u ˙ 2 = f ( u ) {\displaystyle {\dot {u}}^{2}=f(u)} where f is a cubic polynomial that depends on parameters a and b as well as constants that are related to the energy and the gravitational torque.
Rotation around a fixed axis or axial rotation is a special case of rotational motion around an axis of rotation fixed, stationary, or static in three-dimensional space. This type of motion excludes the possibility of the instantaneous axis of rotation changing its orientation and cannot describe such phenomena as wobbling or precession .

For dogs and cats, a 9 point body condition score (BCS) system is used to identify whether they are above their ideal weight status. [5] Scores 1-3 indicate 'too thin', 4 and 5 are 'ideal', 6 is 'above ideal', 7 is 'overweight' and 8 and 9 are 'obese'.
