90 Antiope approximate shape scaled one in two million

cults3d

This model was made using the data from Bartczak (2014), I just resize, soften and simplified the models using Windows 3D Builder to share the same scale as other objects. 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. 90 Antiope Antiope is the best example of a double asteroid, because it is composed of two bodies of nearly the same size, orbiting each other. There isn't a official definition of a binary object, so Antiope is the name of the bigger body; while the other is just its satellite. The distance between their centers of mass is 170 km, nearly two times their diameters, which means that the minimum distance between them is equal to one diameter. The most similar to a binary object in the Kuiper Belt is the Sila-Nunam system, with the two component of 250 km; the most similar to a double dwarf planet is Pluto and Charon system, with the diameter of Charon a half of that of Pluto; and the most similar to a double planet in the Solar System is the Earth and Moon system, being the Moon's diameter 27% of that of the Earth.
