Gravity Model of an Asteroid


Currently, I am working on modeling the gravitational field of a fictional asteroid. For this purpose I use a (non-spherical) stone as a template.

 

Firstly, I have photographed the stone from different views and then I have put a grid over the different views and put the resulting grids together three-dimensionally. This grid is the basis for the "cube approximation" - for which I have decided. In this approximation the three-dimensional body is imitated by cubes. The accuracy of the model is influenced by the size and arrangement of the cubes. To reduce the computational cost, I will use very large cubes and assemble them according to an orthogonal grid.

 

The following pictures show an impression of the first steps of my modeling. From time to time I will update the progress and at the end I will present a detailed article about my procedure and my results here.
