km/h (VERY slow)
Mars
Phobos
-Tidally locked to Mars
-Closest natural satellite to
any planet
-Shaped like a flattened loaf
of bread
-Parallel grooves
-Will eventually crash into
Mars
-Largest crater is called
Stickney
-Possibly a captured satellite
-Revolve in same direction as
Mars, but smaller orbit so
rotates faster
-Diameter: 1/2 the size of
Earth
-Density: 3.934 g/cc
(much lower than Earth)
-Rotation period: 1.026
(almost same as Earth)
-Axial tilt: 25.19 degrees
(almost same as Earth)
Deimos
-Tidally locked to Mars
-Smaller
-No grooves
-Smoother due to thicker
layer of dust on its surface
(fills craters)
-Possibly a captured satellite

Document Summary

Smoother due to thicker layer of dust on its surface (fills craters) Axial tilt: 25. 19 degrees (almost same as earth) Has water slush ocean beneath a solid ice cover. Layer of liquid water beneath icy surface (heat comes from radioactive decay from interior) Appears to have continents, oceans, sand dunes, volcanoes. Albedo resembles that of fresh snow or ice. Fountains of icy salt water and snow spew from troughs at south pole. Density: 0. 687 g/cc (very low float on water) Rotation period: 10. 5 hours (fast bit slower than jupiter) Axial tilt: 26. 73 degrees (enough to see rings from. Rotational period: 17 hours & 15 mins heated by radiation from. Dark material has flooded the floors of some craters. One mountain which rises at least 20 km above the surface. Most craters small (small debris remaining after formation) Melting period in which craters were flooded by water. Network of faults suggest at least one episode of tectonics.
