{{site specific term}}
* Gravity Much lower than the one of planets
* Gravity much higher than what is considered micro-gravity (minute residual tidal forces and such)

== Possible lower limits ==

* Gravity of human built structures?? This will grow though ...
* Gravitational effects well perceptible by human senses without advanced measurement devices – e.g. drift around and in caverns inside of asteroids – this one seems better but still vague

== Possible upper limits ==

* Everything that a body not rounded by it's own gravity can deliver. Asteroid [[Vesta]] 0.025g ~ 0.25m/s^2 ? – this is already pretty high
* Gravity of the biggest asteroid in the [[asteroid belt]] – the dwarf-planet [[Ceres]] 0.029g – similar – seem too high
* Gravity of the biggest metallic asteroids ([[Psyche]] ~0.144m/s^2)
* For humans dangerous fall heights are notably bigger than optimal colonization cavity diameter (a few 100m) – this one is nice but wishy-washy

=== Safe fall in a in a colonization cavern ===

We know from Earth that a fall from 0.5m height @ 9.81m/s^2 is rather endurable. 
So: v_max = sqrt(2*g*h) = sqrt(2*10m/s^2*0.5m) = ~3.2m/s

Assuming a cavity size of 200m 
a_max = v_max^2/(2*d_cavity) = 10(m/s^2)^2/(2*200m) = 1/40m/s^2 = 0.025m/s^2 
– that is crudely rounded about one eighth of what the larges asteroids have to offer (see above) 
– so silicatic asteroids with half the diameter of the biggest ones are already small enough to are quite safe for ~200m diameter colonization caverns.
