WebSep 13, 2024 · And Uranus makes a complete orbit around the Sun (a year in Uranian time) in about 84 Earth years (30,687 Earth days). Uranus is the only planet whose equator is nearly at a right angle to its orbit, with a tilt of 97.77 degrees – possibly the result of a collision with an Earth-sized object long ago. WebThe 21,000-year perihelion cycle and the 41,000-year obliquity cycle do in fact appear to be present in the climatological record. (Note: somewhat different periods for these cycles …

The orbit becomes either more round or more elliptical at these intervals. The shape of the orbit is known as its "eccentricity." A related aspect is the 41,000-year cycle in the tilt of the Earth's axis. Glaciation of the Earth also occurs every 100,000 years.
