Neptune's
Pluto is a planet Pluto was a planet but NASA stated that pluto was not a planet but a dwarf planet. the requirements for becoming a planet Because Pluto is not large enough to "dominate" its orbit, it is not a planet. (Neptune is about 8000 times more massive than Pluto, so Neptune is a planet and Pluto is a dwarf planet.) It must be an object which independently orbits the Sun (this means moons can't be considered planets, since they orbit planets) It must have enough mass that its gravity pulls it into a roughly spheroidal shape It must be large enough to "dominate" its orbit (i.e. its mass must be much larger than anything else which crosses its orbit)
Pluto's orbit is quite unusual. It takes 248 Earth years for Pluto to complete one orbit around the Sun. Its orbit is also more oval-shaped, or elliptical, than those of the 8 major planets. That means that sometimes Pluto is a lot nearer to the Sun than at other times, At times Pluto's orbit brings it closer to the Sun than Neptune.
Neptune has an odd orbital property. The orbit of Neptune crosses the orbital path of the dwarf planet Pluto, so there are times when Pluto is closer to the Sun than Neptune.
Pluto has a highly elliptical orbit which is at a steep angle to the ecliptic.The ecliptic is the plane that contains the sun's apparent motion through the skies from earth's point of view. Pluto is a K.O. (Kuyper Object, an object from the Kuyper Belt, more like an icy comet than an asteroid). It does travel within the orbit of Neptune for a few years out of its long orbit, but never in a way that will bring it crashing down onto Neptune. Pluto is locked into a special harmonic relationship with Neptune which prevents that from happening. For every 2 orbits of Pluto there are 3 orbits of Neptune. They are never close enough to collide. Pluto spends the vast majority of its orbital time in the Kuyper Belt, beyond Neptune's orbit.
Pluto is more like an inner planet and is very cold, the outer planets are gas. The outer planets are cold Pluto.Aside from being, on average, the farthest planet from the Sun, Pluto and its orbit have several characteristics that make it unique. Its greater distance means its orbital period of 248 years is the longest of all planets. Its orbit has the highest eccentricity, which means that its distance from the Sun varies more than other planets. Its orbit is so far from circular that it can actually be closer to the Sun than Neptune at times.The plane of Pluto's orbit is also tilted the most compared to the rest, taking it further north and south of the Earth's orbital plane than the otherplanets.
Pluto has the longest orbit in length as it is further away from the sun than the other planets. If we model the orbit of all the planets as perfect circles, we can see that planets further from the sun give orbits which are larger circles, and larger circle have larger circumferences, which are the longer orbits. Even if the planets orbited at the same speed, Pluto would take longer to orbit as it has further to travel. Pluto doesn't orbit at the same speed as other planets - it orbits more slowly. This means it takes even longer to orbit the sun. It orbits more slowly as it is further out and the sun exerts less of a gravitational force on Pluto than on the other planets, and it is this gravitational force which causes objects to orbit around the sun. In fact, the sun exerts 1600 times as much force on Earth than on Pluto.
Pluto takes 246.04 years to orbit the sun once
Pluto has an eccentric and inclined orbit compared to the planets in our solar system. It is also known to cross Neptune's orbit at times, making it a "dwarf planet" rather than a full-fledged planet. Additionally, Pluto's orbit is not perfectly circular like most planets, leading to variations in its distance from the Sun over time.
Yes, Pluto is closer to the Sun than Neptune for a ~20 year period every 228 years. The last time it was closer to the Sun than Neptune was 1979. This happens because Pluto has an eccentric orbit that is also highly inclined, Pluto's size\mass is not directly involved in this process in any way.
No. Pluto's orbit is more than 4 times as larger and takes more than 8 times as long as Saturn's.
No normal planets actually switch orbits the way that Janus and Epimethius (Saturn moons) do in a co-orbit. Some Dwarf Planets sometimes are closer or farther from the sun than other kindred Dwarf Planets depending on their locations along their orbits. Pluto is sometimes closer to the sun than Neptune. Haumea is usually further from the sun than Pluto but sometimes is closer. Makemake has the same relationship with Haumea. Eris is usually the farthest but sometimes in its elliptical orbit is closer to the sun than Haumea.
