This model was based on Naidu (2020), remeshed, scaled and divided using Microsoft 3D Builder. The shape of the satellite Dimorphos is just an ellipsoid that fits the radar images. The next year we will have better images from this pair from the DART Mission.
The file's names explained:
name_1_x_10_y.stl is 1 : x * 10
y. So _1_6_10_7 is 1:600000000 or one in 60 million.
65803 Didymos
This is a typical small asteroid with a satellite. It was targeted for the DART mission because that satellite is so small overall that can be affected by a man made impactor. In July of 2022 the probe DART will impact its 500kg weight in the asteroid's moon Dimorphos. It is expected that the impact will shorten its orbit by 10 min. This experiment will help to develop a deflection plan to prevent future asteroid impacts on our planet.
