Planets are NOT elliptical in shape, they are basically spheres. However their spherical shape is distorted by the centrifugal forces resulting form their spin. This makes their equators fatter and their shape becomes that of an "Oblate Spheroid".
All of the planets are spherical; none are appreciably oblate. In fact, being spherical is one of the elements of the 2006 IAU definition of "planet".
Probably the biggest deviation from spherical is the mountain Olympus Mons on Mars; it is the highest mountain that we know of in the solar system. However, our exploration of Venus and Mercury are still in the very early stages; there are many surprises yet to be found there.

∙ 10y agoNeptune has the longest orbit at about 18 billion km (11 billion miles). Neptune requires nearly 165 earth years to complete one orbit. Mercury has the most elliptical (eccentric) orbit out of our solar system's eight planets.
This question seems to be about Pluto, but that's not classed as a planet now. Before 2006, when Pluto was "demoted" to dwarf planet status, then Pluto would have been the correct answer.
Data for dwarf planet Eris: The eccentricity of its orbit is 0.44, greater than any planet, and its year is 557 Earth years.
One of the longest known orbits in solar system, apart from comets, is that of
Sedna. It takes about 10,000 Earth years to complete its orbit.

The eccentricity of Eris, at 0.44, is about twice that of Pluto. Eris is tilted 44° to the ecliptic, more than twice that of Pluto. The planet with the greatest orbital inclination is Mercury, at 7°.

∙ 11y agoYou probably meant "least circular orbit". Astronomers call this the "eccentricity" of the orbit. Mercury is the answer.
If you just meant the "largest orbit", the answer is Neptune.

The plane with the smallest orbit is Mercury, and the planet with the largest orbit is Neptune.
What is the orbit of a planet called?
The motion of the planets are elliptical motions
What is the curved path of a planet?
Elliptical Orbit.
Which planet has an oblique elliptical orbit?
Pluto has the most oblique orbit. All the planets have elliptical orbits, however Mercury has the most elliptical orbit since Pluto is now considered a dwarf planet. This information is provided by the Royal Astronomical Society of Canada and available online [see related links].

Which planet has the smallest orbit and the largest orbit?
The plane with the smallest orbit is Mercury, and the planet with the largest orbit is Neptune.
Where is the dwarf planet churon lacated in the solar system?
There is no dwarf planet named Churon. Charon is a real object, though. it is not a dwarf planet, however: it is the largest moon of the dwarf planet Pluto, which has an elliptical orbit that lies mostly beyond the orbit of Neptune.
