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. WebAVI Movie. Earth's Orbit with Obliquity - Animation of Earth over one full revolution around the Sun. A blue arrow showing the Earth's spin axis demonstrates the concept of obliquity.
