As far as I know, there is no special name for this, in astronomy.
Continental Plates
Neptune and Mercury are the two planets farthest apart in our solar system. This is because Neptune is the farthest planet from the Sun, while Mercury is the closest. The distance between Neptune and Mercury can vary greatly due to their elliptical orbits around the Sun.
Seafloor spreading
Neptune and Mercury are the two planets farthest apart from each other in terms of distance in our solar system.
Neptune and Uranus are the two neighboring planets in our solar system that are farthest apart. Despite being adjacent to each other in order, Neptune is the farthest planet from the Sun while Uranus is the seventh planet from the Sun.
Pluto and Eris
When two plates move apart from each other, it creates a divergent boundary. Magma from the mantle rises to fill the gap, solidifies, and forms new crust. This process is called seafloor spreading and is responsible for the formation of mid-ocean ridges.
A long, linear crack that forms as two tectonic plates move apart is called a mid-ocean ridge. This type of boundary is where new oceanic crust is created as molten rock rises up from the mantle and solidifies along the spreading center. Over time, as the plates continue to move apart, the new crust forms a continuous ridge on the ocean floor.
The long crack that forms as two tectonic plates move apart is called a rift. It is typically seen in divergent plate boundaries, where the plates separate and magma from the mantle can rise to create new crust. Over time, as the plates continue to move apart, the rift can widen and eventually lead to the formation of a new ocean basin.

This process is called seafloor spreading. As the two plates move apart, magma rises from the mantle to create new crust at the mid-ocean ridge. This process helps explain the movement of Earth's tectonic plates and the reshaping of the ocean floor.
Mars and Jupiter are about 856,000,000 miles apart on average in their orbits around the Sun.
