89 Julia scaled one in four million

cults3d

This model was made using MATLAB R2016a on the topographical map from Vernazza (2018). 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. 89 Julia Julia is a medium to big sized S-type asteroid. It has a notably big crater, with a half of the asteroid's diameter. It was created relatively recently, 30 to 120 million years ago, with the impact of an 8 km body. The Julia Family was created from the debris ejected in this event. Type: Asteroid. Orbit: Sun.
