Similar to my post of Neptune, this model of Uranus does not represent a topography because it has not a solid surface. Instead of that, the model relief represents the height of the clouds by its albedo, in the time the image was taken. Gas planets have different wind speeds for any latitude, so the storms and clouds are constantly changing its positions. It is based on the high contrast images from the Keck telescope.
The ring system of Uranus is quiet complex. To make it scalable, the rings are reduced to three zones, with the outer one the brightest.
The file's names explained:name_1_x_10_y.stl is 1 : x* 10y. So _1_6_10_7 is 1:600000000 or one in 60 million.
Uranus
Uranus is particular among Solar System planets because its extreme axial tilt, 98° by prograde rotation. It is thought that this tilt is because an early massive collision with a super-Earth sized protoplanet. The moons of the system are coplanar with its rotation, so they probably formed after this event. It has five mayor moons: Miranda, Ariel, Umbriel, Titania and Oberon. Another oddity of this planet is its low temperature, lower to that of Neptune. This could be the result of the previous collision, that helps to evacuate the internal heat quickly. Another possibility is that the extreme seasons in Uranus create a storm system capable of block the heat transfer from its interior. Uranus is the lightest of the gas planets, and the third in size, slightly larger and less dense than Neptune. The two ice giants has about 4 times the diameter of Earth, and 14.5 times its mass. The surface gravity, if we define the "surface" as the 1 bar altitude, is comparable with Earth's one: 0.869 m/s2, meaning we could stand easily in its surface if it had one. Uranus has a complex ring system, with some rings with incomplete arcs or denser arcs within the ring. Only the ε ring is bright enough to be visible. Ice giants are common among known exoplanets, because they are easier to detect than smaller planets, and they are more common in lower orbits than bigger ones.
