WebIt is postulated here that the primordial Earth acquired an obliquity of ∼ 70° (54° < ɛ < 90°) from the Moon-producing single giant impact at ∼ 4500Ma (approach velocity ≈ 5-20km/s, impactor/Earth mass-ratio ≈ 0.08-0.14). Secular decrease in ɛ¯ subsequently occurred under the dominant influence of dissipative core-mantle torques.

In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane; equivalently, it is the angle between its equatorial plane and orbital plane. It differs from orbital inclination. At an obliquity of 0 degrees, the two axes point in the same direction; that is, the rotational axis is perpendicular to the orbital pla… fsp champ usvWebObliquity of the ecliptic is the term used by astronomers for the inclination of Earth's equator with respect to the ecliptic, or of Earth's rotation axis to a perpendicular to the ecliptic.
