Face océane Face continentale Figure 13 : The UMMO planet (reconstitution based on the planisphere). No one can say if these information corresponds to reality or not. But if one suppose it is the case, here is what the Earth expeditionaries would find there. On one half of the planet, we would find a unique continent and on the other a vast ocean. The surface covered by the oceans would be equal to 62% of the one of the planet. its radius would be about 7250 km (against 6400 for the Earth). Titanium would be abundant in the floor, with the form of minerals 25. The gravity would be stronger. If we went on UMMO, our weight would increase of 20%. Inversely, the Ummits, when they walk on our floor feel lighter. The earth is slightly flat on its poles, because of the centrifugal force coming from its rotation. On UMMO, that would be the contrary. The altitude on the poles would be 15 km higher than on the rest of the planet. The Ummits explain that by the fact that the magnetic field on UMMO 26 is quite strong (thousand time bigger than the Earth field, 500 Gauss against 0,4 Gauss). The climate would be relatively cold, continental, with big temperature contrasts. The inclination of the rotation axis of the planet is 18% instead of 23% for the Earth. The seasons would be less pronounced. But can we speak of seasons went the planet turn around its star in two and a half terrestrials months. The local sun, the star Iumma, a dwarf of class M, would be less hot than our sun, and UMMO would have a smaller orbit 27. The planet would have no satellites, no moons. The nights would be then very dark and much colder than ours, even at the equator 28. The night temperature would 102
