While I realize that most people tend to wish knowledge of distance with respect to "where they are"... Most measurements in discussions of the Solar System measure distances from the Sun. Since all of the planets orbit the Sun, it depends upon where the planets are in their own individual orbits as to how far they are from one another. All of the orbits are eliptical in shape, but the following answers are estimates assuming a more circular orbit for ease of calculation:
Sun to Earth = 93,000,000 Miles
Sun to Neptune = 2,800,000,000 Miles
So, at a time when the two planets were closest together in their orbits, (Earth and Neptune both on the same side of the Sun) the distance would be 2,707,000,000 Miles.
When they are fartherest apart (Earth on one side of the Sun, and Neptune on the other) the distance would be
2,893,000,000 Miles.
Those are some fairly long distances if you think about it.
Consider that the circumference of the Earth (distance all the way around it) is about 25,000 Miles. When you think like that, the numbers above look really big.

Its as far away as Neptune is, since Triton orbits Neptune. And the distance varies, since Neptune and Earth both have elliptical orbits and move around the sun at different velocities. When Neptune and Earth are closest, they are at 28.75 AU apart. The time it would take to get from Earth to Neptune would vary, depending on the velocity of the spacecraft and the trajectory it took. New Horizons was launched in 2006 and will cross Neptune's orbit in 2014 (8 years). Voyager 2 launched in 1977 and flew by Neptune in 1989 (12 years).

Far enough away that if the Earth didn't rotate or orbit the Sun but everything went around it then Neptune would be just outside of the area where an object orbiting Earth fast enough to go around once in 24 hours would be going the speed of light.
LOL, silly geocentrists (yeah, they exist).

it's about 2.68 billion miles away from earth or 4.3 billion km. Of course, this isn't a very fair question because the distane between two moving objects is of course changing with time. But it should be somewhere between 4.3 billion km
and 4.7 billion km at any given point in time. Please go to http://nssdc.gsfc.nasa.gov/planetary/factsheet/neptunefact.html for more information.

If I could I'd rearrange the planets to put the earth and neptune together!

Approximately 4388 million km from the earth... ha...this is where a student comes handy!
