VENUS Motions orbit: orbital period = 225 days rotation: rotation period = 243 days o siderial "day" is longer than a "year" o (solar day = 117 days) rotates "backwards"  Interior observe NO magnetic field and very slow rotation Even with slow rotation we expect at least a small field unless: 1. core is not molten - (Why not ?) 2. Venus is undergoing a field reversal !! 3. model is wrong Venus is differentiated => was molten at some time continental drift ? no strong evidence - but some local cracking and motion volcanoes ? definitely active within last 10 million years many dormant volcanoes gasses in atmosphere from volcanoes suspect that Venus may still be active
