- The C-type (chondrite) asteroids are most common. They probably consist of clay and silicate rocks, and are dark in appearance. …
- The S-types ("stony") are made up of silicate materials and nickel-iron.
- The M-types are metallic (nickel-iron).
Do asteroids have gravity?
Asteroids, without artificial gravity, have relatively little gravity in comparison to earth. Without gravity working on the human body, bones lose minerals, and bone density decreases by 1% monthly.
How many moons do asteroids?
More than 150 asteroids are known to have a small companion moon (some have two moons). There are also binary (double) asteroids, in which two rocky bodies of roughly equal size orbit each other, as well as triple asteroid systems.
Where do asteroids come from?
