This satellite view picture, showing how Grenoble and Phobos compare.

Ludovic explains: “What better way to give a scale than to compare with actual things on Earth?

If you carefully look at the center of the picture, you’ll see 2 helicopters, still quite far from the “big rock”.

We can see there that the entire town of Grenoble would easily fit inside Stickney crater, Phobos’ largest crater (on the right).”

With a mean radius of 11.1 km (6.9 mi), Phobos is 7.24 times as massive as the second moon Deimos. It is named after the Greek god Phobos (which means “fear”), a son of Ares (Mars). Both moons were discovered in 1877.
