The scale of Phobos

This new picture is to be an exception here, as it is not located on Mars ! Since I've started being interested by Mars, I am fascinated by the scale of the planet and its features, and of course, there is Phobos, its largest moon (the other one being Deimos). What better way to give a scale than to compare with actual things on Earth ?
So, here is Phobos standing over my town Grenoble in the Alpes (eastern France). Phobos' dimensions are 26,8 x 18,4 km. If you carefully look at the center of the picture, you'll see 2 helicopters, still quite far from the "big rock".
Here too is a companion picture showing in satellite view how Grenoble and Phobos compare. We can see there that the entire town of Grenoble would easily fit inside Stickney crater, Phobos' largest crater (on the right).

I made this with TheGimp on Linux-Ubuntu. A 5 hours work.

In the Greek Mythology, the twins Phobos and Deimos ("fear" and "dread") were god sons of Ares ("Mars").

Nice work! I also live in Grenoble (Ile Verte). I am into computer programming, so just imagine that there is a language called D, which was formally known as... Mars and his standard library is called... Phobos.

FYI, just see the little discussion that I started there on this topic:
