944 Hidalgo scaled one in one million

cults3d

I did not render this model, I just softened and simplified the model of Hanuš (2016) available in the 3D Asteroid Catalogue site, to make it less "poly".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. 944 Hidalgo This was the first centaur discovered, previously to being recognised as a different group of minor planets. It has the color of a D-type asteroid, which implies that it's probably composed of organic rich silicate and water ices, like several other centaurs and most of Jupiter trojans. They may be originated in the Kuiper Belt, scattered inward by close encounters with Neptune. Type: Centaur. Orbit: Sun. Orbital period: 13.76 yr. Rotational period: 10 h 4min. Composition: Carbonaceous and ice. D-type. Density: ? Dimensions: 38 km Model scale: 1:5x105 (8cm) 1:1x106 (4cm) References New and updated convex shape models of asteroids based on optical data from a large collaboration network.
