Answer 4

if you have seen the sun, you have seen 93 million miles and other stars are much more distant.. it all depends on the amount of available light.

Answer 5

With the Hubble Space telescope, to the edge of the Universe.  The limit is actually the resolution of the human eye.  For example you look at a "star" with the unaided eye.  Then look at the same point of light with a telescope.  The "star" is actually a cluster of stars but the resolution of the eye was not able to distinguish the starts.  Use this link to read about the measurement of visual acuity:  http://en.wikipedia.org/wiki/Eye#Acuity
