Pluto orbits in elegant arrangement with the giant planets

Abstract

Pluto has such a peculiar orbit that people have wondered how it exists. In our new work, we found that the orbital architecture of the giant planets lies in a Goldilock's zone that allows for the survival of Pluto and many other similarly peculiar trans-Neptunian objects. A slightly different arrangement of the giant planets would’ve ejected Pluto long ago from the solar system.
