Thus, Titan is probably the satellite most likely to support life of any kind. Asteroids exist between the orbits of Mars and Jupiter. They are irregularly shaped terrestrial bodies because of the abundance of metal and rock. Collisions between asteroids are infrequent but can produce meteors. Some theories concerning the origin of the asteroid belt state that the asteroids could be the remains of a planet ripped apart by the tidal forces of Jupiter and Mars.
Tidal forces rely on gravity.
Under the presence of sufficient gravity, bodies of matter experience shifting of various parts of the body, usually the outer layer. Asteroids would be most helpful to humans for the exploitation of resources, such as metals. Humans could not survive on an asteroid without supplemental oxygen. However, a trip to an asteroid would be quite enjoyable. On a typical asteroid, one could make a running jump and dunk a basketball into a goal approximately a kilometer away.
