Exploring the Martian Moons: Deimos and Phobos

Deimos and Phobos are the two moons of Mars, named after attendants of the Roman war god Mars. Both moons share dark, C-type surface materials similar to carbonaceous chondrite asteroids found in the outer asteroid belt. While some scientists speculate that they are captured asteroids, there are counterarguments against this theory. Deimos has a smoother appearance due to partial filling of craters, while Phobos showcases striated patterns from impacts. Together, they provide intriguing insights into the Martian system and its history.

Presentation Transcript

  1. Deimos • Deimos [DEE-mos] (panic) is a moon of Mars and was named after an attendant of the Roman war god Mars. Deimos is a dark body that appears to be composed of C-type surface materials. It is similar to the C-type (blackish carbonaceous chondrite) asteroids that exist in the outer asteroid belt.

  2. Deimos • Some scientists speculate that Deimos and Phobos (the other martian moon), are captured asteroids; however, other scientists present arguments counter to this theory. Both Deimos and Phobos are saturated with craters. Deimos has a smoother appearance caused by partial filling of some of its craters.

  3. Phobos • Phobos [FOH-bohs] (fear) is a moon of Mars and was named after an attendant of the Roman war god Mars. Phobos is a dark body that appears to be composed of C-type surface materials. It is similar to the C-type (blackish carbonaceous chondrite) asteroids that exist in the outer asteroid belt.

  4. Phobos • Some scientists speculate that Phobos and Mars' other moon, Deimos, are captured asteroids. However, other scientists point to evidence that contradicts this theory. Phobos shows striated patterns which are probably cracks caused by the impact event of the largest crater on the moon.
