In the solar system, that planet is Neptune.
Actually no, it's Pluto. Lying in what is known as the Kuiper Belt, it is 7.4 billion km away from the Sun at it's furthest point of orbit, and was discovered in 1930 by the astronomer Clyde W. Tombaugh.
So, is the right answer "Neptune" or "Pluto"?
I say it's Neptune because Pluto was "demoted" to "dwarf planet" status in 2006. Pluto is not considered a true planet now by most astronomers.
Planets are separated most when they happen to be on opposite sides of the Sun. Neptune and Uranus would be the furthest apart in that condition, something like 49 astronomical units (49 times 150 million km) but it won't happen for many years.
Neptune. (It used to be Pluto, but in 2006 the International Astronomical Union "demoted" Pluto to the status of "dwarf planet".)
Neptune, at an average distance of 30.1 AU is the furthest planet.

Two planets are at their greatest separation when they are on opposite sides of the Sun. When a planet is at its greatest separation from the Earth the planet is said to be at superior conjunction. It cannot be seen until it has separated out from the Sun, which usually takes a few weeks at least.
The inner planets are closer together than the outer ones.
The speed of light is normally used to tell the distance between planets. The distance between cities is measured in miles.
No. They are much greater.
The two neighboring planets with the greatest distance between them is Neptune and Uranus. This happens when they are at the opposite sides of the Sun at approximately. They are 4500 million miles away from each other.
If two planets are in orbits with radii of R1 and R2, the distance between them varies from R2-R1 to R2+R1.
As the names suggest, the inner planets are closer to the Sun than the outer planets.

the distance from the planets is 6.5 million miles between each planet.

The inner planets are closer together than the outer ones.
These distances compare from a long distance but one that is not nearly as far as the distance between the outer planets.

No. They are much greater.
The two inner planets Mercury and Venus move in retrograde motion (east to west along the ecliptic) between their time of greatest distance from the Sun (elongation) to the east as an evening star and their greatest elongation west as a morning star.
