Mercury and Uranus are the two planets that are farthest apart.
That would be Mercury and Neptune.
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.
It really could be close to anything. IT would depend where 1.1 billion miles away it is. (i.e. Up? North? Upnorth?) and, the position of the planets in their orbits.
The two planets with overlapping orbits are Neptune and Pluto. These are the only two planets that have overlapping orbits.
When the two planets are at their closest they are 33,926,867 miles apart. When they are furthest apart 249,169,848 miles.
Mercury and Uranus are the two planets that are farthest apart.
The two farthest apart NEIGHBORING PLANETS are Neptune and Uranus!
The distance from Venus to Earth changes according to where the two planets are in their orbits and therefore in relation to each other. When at their closest they are 23.7 million miles apart and when furthest away they are 162 million miles apart.
Pluto and Eris
The distance between the two planets can be as close as (about) 35 million miles (56.3 million km), or be as much as 222 million miles (357 million km) apart.
That would be Mercury and Neptune.

As far as I know, there is no special name for this, in astronomy.
It depends on the scale of the map.
Both Venus and Earth are in orbit around the sun, with different periods. Venus' distance from the sun is 72.8% of Earth's average distance. The nearest that the two planets can approach each other is when both are on the same line from the sun and on the same side. Then they're 0.272 AU or about 25.3 million miles apart. The farthest apart that the two planets can be is when they're exactly opposite each other with the sun in the middle. Then they're 1.728 AU or about 160.7 million miles apart. The distance between Earth and Venus is always somewhere between these extremes.
The two objects are about 3.66 Billion miles apart.
