Explanation:
Diminutive Deimos
is the smallest of the two tiny Moons
of Mars.
Potato shaped and barely 6 miles wide
this asteroid-like body was visited by the Viking 2 orbiter
in 1977.
This image was made when the spacecraft approached to within
18 miles of Deimos' surface.
It is one of the most detailed
pictures of a celestial body ever taken
by an orbiting spacecraft - the field of
view is less than a square mile and features just under 10 feet across
are visible.
Craters and large chunks of rock are seen scattered on
the surface. Some of the craters appear to have been covered by a layer
of regolith (soil and broken rock).
