Obliquity Variability of a Potentially Habitable Early Venus
Description: Researchers investigate how the obliquity would have varied for a hypothetical rapidly rotating Early Venus. The obliquity variation structure of an ensemble of hypothetical Early Venuses is simpler than that Earth would have if it lacked its large moon, having just one primary chaotic regime at high prograde obliquities. The authors of this article note an unexpected long-term variability of up to ±7° for retrograde Venuses. Low-obliquity Venuses show very low total obliquity variability over billion-year timescales-comparable to that of the real Moon-influenced Earth. [Source: Astrobiology]
