If I have an 1 mW yellow laser pointer of 589nm, up to how many meters is the dot of the beam visible to human eyes?
(up to how many meters is the laser visible)
Thanks a lot!

That depends on a whole load of things. Ambient light levels, atmospheric conditions, beam specs.

With good weather will it make it to 10 meters?
You'd be hard pushed seeing it in direct sunlight, even on a white surface. Should be no problem at night on a white surface.
