Neptune is visible (using a good telescope) in the evening sky from all over Earth at the moment (December 2008)
If you go out in the evening there will be two very bright objects above the south western (from the norther hemisphere) horizon. The lower one is Jupiter and the higher one (and brightest) is Venus. If you join the two up with an line and keep going upwards and towards the south you enter the constellation Capricornus. Neptune is at present in the tail area of Capricorn.
Only at night and you have to know exactly where to look Neptune is very faint even in moderately large telescopes. In late September 2009 it will be in Capricorn not all that far from Jupiter which is very bright. (see link)
Neptune is visible from Earth at many times during the year depending on your location. It is not visible with the naked eye, so you will need a telescope.
As long as you stay on the Earth, Neptune
is never visible without optical aid.
When you've got a telescope, for a start.
Not from the Earth it can't.
You could see Neptune from Earth with a telescope if you knew exactly where to look.
Yes, Saturn is readily visible to the naked eye. But you can't see the rings and moons without a telescope.
Yes, but it has to be a pretty good telescope, and you have to know just where to look. Neptune will look like a fairly faint star, you wouldn't know it was a planet unless you waited for days and observed it moving.
It is too far away, too small, and doesn't,reflect enough sun light to make it visible without a telescope.
No. No. You need a telescope to see Neptune.Nope... Neptune cannot be seen from the Earth without a telescope.

Uranus is barely visible to the naked eye on very dark nights, to those with good eye sight. Neptune requires a telescope to see.
Pluto is not visible without a telescope.
They can be visible from Earth without the aid of a telescope.
All of them with the exception of Neptune.
Not from the Earth it can't.
All of them Without a telescope: Mercury, Venus, Mars, Jupiter, Saturn and on a very good night Uranus. With a telescope: All of the above plus Neptune.

Neptune is the only planet in our Solar System that requires a telescope to see it.All the others are visible to the naked eye.Pluto, which is still counted as a planet by many people, also needs a telescope.
no because its far away
Neptune but only on a very good night i think
