We are living in a golden age of asteroid and comets exploration. As of 2021, 25 objects have been visited by a robotic probe, and all space agencies aorund the world have a mission planned or under consideration for the next decade.

As a professional planetary scientist, I have written many tools to process the data I use, especially in the field of cometary and asteroid science. As much as I can, I like to share those programs freely with the community, in the hope they may be useful for others.

This website contains my publicly available software, and is maintained on my free time. You can find more information about my research on my personal page.


All tools can be accessed via the navigation menu on this page.

Open source

Science must be reproducible. This means that not only data has to be publicly available, but also the tools that led to a given interpretation.
In that spirit, all javascript code presented in this website is distributed under a BSD license, available in the header of each file.

The code can be consulted directly from the sources of these webpages (Ctrl+U in Firefox and Chrome).
It can also be accessed and improved through a public repository hosted by Bitbucket.

The source code of shapeViewer is very complex and open sourcing the more technical parts requires properly commenting and organizing the code, which will take some time. Meanwhile, all algorithms and data necessary to evaluate the scientific output of the software are provided in the User Manual.

Terms of use

I kindly ask each publication making use of my tools to include the relevant acknowledgement:
