Apparent magnitude - +1.6- -3.0

(nighttime)- -73°C
Poles- 0°C to -102°C.

8. NATURAL SATELLITE

Deimos (dead)- is composed of rock rich in
carbonaceous material, much like C-type asteroids and
carbonaceous chondrite meteorites.
It is cratered, but the surface is noticeably smoother
than that of Phobos, caused by the partial filling of craters
with regolith.
The two largest craters, Swift and Voltaire
