This models were made using MATLAB R2016a with a topographical map of the Earth, including the seafloor.Like other models made by this way, the total relief is exaggerated, because proportional relief would make the terrain features too small to be noticed. Most of the coast lines are diffuse or not visible, because the continental shelft has not so different height than the coast. I've upload this model in 3 scales: one in sixty million, to compare with the biggest moons in the solar system; one in 120 million, to compare with terrestrial planets; and one in 250 million to compare with bigger objects like exoplanets (pending), in this scale Neptune and Uranus are nearly 20cm in diameter.
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.
Earth is the only astronomical object inhabited by humans, or any kind of life; the biggest terrestrial object in the Solar System; and the only one where water can be liquid in its surface. It also has the third most dense and massive atmosphere of a terrestrial body, after Titan and Venus. It has the biggest satellite, the Moon, compared to the mass and size of its parent body, of any planet. It is the only object with current tectonic activity, many others show signs of ancient activity, especially icy bodies. This is possible because most of the Earth's surface (70.8%) is covered by water, that reduce the viscosity of the crust, allowing the movement of the tectonic plates. This plates are moving constantly changing the possition and distance of the continents. The Earth has also 5 pseudo satellites, one troyan in the L4 point, and its orbit is crossed by many Near Earth Asteroids.
