Kepler's first law says Neptune has an elliptical orbit with the Sun at one focus. The same goes for the other planets.
Neptune would finish last, because it has the longest orbit and the slowest velocity.
Saturn's orbital period is about 29 and a half Earthyears. Meaning it takes about29.5 Earth years forSaturnto orbit the Sun once. Twice would make it about 59 years.
Yes, the larger the mass, the stronger the orbit, because for that much mass the orbit has to be strong; otherwise, it would float out deep into Dark Matter.
There would be no orbit. You have to have a body to orbit around and without a star or other planet to orbit around, it would just move in a straight line.

The period of Earth's time that would be considered longest is the Precambrian Era.
Revolution of a planet can mean two things:* orbital period - the time it takes to orbit the Sun - then the answer is Neptune, the farthest planet. Neptune takes about 165 years to orbit the sun once. It is thus the planet in our solar system with the longest period of revolution. The dwarf planet Sedna may take as long as 12,000 years to orbit the sun.* rotational period - the time it takes to spin on the axis - then the answer is Venus. Venus has the longest period of rotation (day) at 243 Earth days.Eris, which is larger than Pluto, orbits once every 557 years.
One of the parts of an ellipse is the length of its major axis. Half that is called the semimajor axis. Kepler's 3rd law says that the time to do one orbit is proportional to the 3/2 power of the semimajor axis. IF the semimajor axis is one astronomical unit the period is one year (the Earth). For a planet with a semimajor axis of 4 AUs the period would have to be 8 years, by Kepler-3.

This depends on whether you count Pluto as a planet or not. If you don't, then Neptune has the longest orbit period (nearly 165 Earth years). If you do, then Pluto has a orbit period of 248.1 years. If you count Pluto, you might also count Sedna which takes 12,050 years. Sedna is 2/3 the size of Pluto and it's 960 times as far from the Sun as the Earth.
Among the two Jurassic period was the longest one.The existence of the period was for about 50 million years whereas permian existed for 35 million years. The duration of Mesozoic era /secondary was 120 million years .
It would approach the sun again, but not for a long period of time, until it has gone through the rest of its elliptical orbit.
Neptune would finish last, because it has the longest orbit and the slowest velocity.
sugarless it has more flavor. sugar gum wears off right away. Trident or Orbit mint would probally be the best.
