Phobos: would you have recognised it under the tiles?

This photo was Unvil’s mystery photo of the day. It was fully hidden under a mosaic of tiles: every close word knocked some down until the answer, “Phobos”， was found.

Phobos in a few words

The larger of Mars’s two moons (about 27 km across), photographed in 2008 by the Mars Reconnaissance Orbiter. Its Stickney crater is 9 km wide; Martian gravity will eventually tear it apart.

The hints

• It is in the Solar System.
• It orbits a planet, but it is not our Moon.
• It is barely 27 km long and is slowly getting closer to its planet.
• Its name means “fear” in Greek; its twin is called Deimos.
