Pluto orbits the Sun in an ellipse and completes its revolution in about 247.9 Earth years, so it has not yet completed a complete orbit since it was discovered.
It is located at a distance from the Sun that varies between 7.37 billion km at aphelion and 4.43 billion km at perihelion.
This last value is curious because it shows how at a certain period of its year, Pluto is closer to the Sun than Neptune, which has an average distance from the Sun of 4.5 billion km, nothing similar occurs among the other planets in the Solar System.
Its orbit has two more characteristics that differentiate it from those of the other planets: it has a marked eccentricity, almost 15 times that of the Earth, and is inclined by 17 degrees with respect to the plane of the ecliptic.
This is because Pluto's orbit is influenced by Neptune and also because this is how the solar system formed it.
In fact, the solar system formed through an accretion disk, concentrated in various points, which then merged and formed the planets.
The chunk of rocky material that formed Pluto may have collided with another chunk of rocky material and thus acquired a slightly chaotic orbit, which became increasingly chaotic over time!
