Pluto Facts - Science@NASA
Pluto's orbit around the Sun is unusual compared to the planets: it's both elliptical and tilted. Pluto's 248-year-long, oval-shaped orbit can take it as far as 49.3 astronomical units (AU) from the Sun, and as close as 30 AU.
Pluto - Wikipedia
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most- massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.
Orbit and Rotation of Pluto - Planet Facts
Pluto’s orbital period is long. It takes 248 years and its orbital characteristics are substantially different from every other planet in our Solar System; a year in Pluto is equivalent to 248 Earth years.

The Orbit of Pluto. How Long is a Year on Pluto?
2017年3月29日 · At its closest, Pluto actually crosses Neptune’s orbit and gets closer to the Sun. This orbital pattern takes place once every 500 years, after which the two objects then return to their...

2024年11月10日 · Pluto's orbit is more elongated, or eccentric, than any of the planetary orbits and more inclined (at 17.1°) to the ecliptic. In traveling its eccentric path around the Sun, Pluto varies in distance from 29.7 astronomical units, at its closest point to the Sun (perihelion), to 49.5 AU, at its farthest point (aphelion).

What Is Pluto? (Grades 5-8) - NASA
2015年8月4日 · Most planets orbit the sun in a near-circle with the sun in the center. But Pluto’s orbit is an ellipse, and the sun is not in the center. Pluto’s orbit is also tilted compared to the orbits of the eight planets. The path on which Pluto orbits is angled 17 degrees above the line, or plane, where other planets orbit. How Is NASA Exploring Pluto?
Why Does Pluto Have Such a Weird Orbit? - Discovery
2020年2月18日 · Relative to the average of the rest of the planets in the solar system, Pluto orbits at a jaunty angle of 17 degrees. This doesn’t sound like much until you compare it something like the Earth, which is a mere 1.5 degrees off.
Scientists explain how the weird orbit of Pluto formed
2022年4月25日 · Pluto’s orbit is determined by its interaction with Neptune. Pluto has an elongated orbit with an eccentricity of 0.25. It is also inclined at an angle of 17 ° to the plane of the ecliptic, in which the major planets rotate. In addition, the orbit of this ice dwarf is unstable.
