As Pluto is no longer considered a planet, the planet with the longest orbital period is Neptune. The Neptunian year is approximately 60,190 Earth days.
Planet Neptune takes the most time to orbit the sun, as it is the farthest away.
Mercury takes the most least time to orbit the sun. It takes 88 days.
PLUTO
Neptune. It would be Pluto, but Pluto is a dwarf planet ( a planet that was a planet, but decided that it wasn't a planet)
the planet that has the most amount of moons is Jupiter which has 67 moons
Neptune orbits the Sun (as do most planets) with an elliptical orbit. When the orbit takes the planet closest to the Sun it is moving faster than when it is furthest from the Sun when on an 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].
It varies from planet to planet. But most planets including our own, orbit the star in an elliptical motion.
Mars has the most elliptical orbit. The earth's is almost a perfect circle
The planet with the most elliptical orbit is Mercury. Second is Mars.
