-- If different parts of the Earth revolved around the sun at different speeds,
then the Earth would have to come apart in pieces. They don't, and it doesn't.
-- The tropical year is the same duration everywhere on Earth.
Mars takes longer to make one orbit of the sun. Its slower, and it also has further to go. Planets orbiting speeds get slower the further you go out.
It would be longer because Neptune is farther away from the sun than Earth is. Then, Neptune revolution is 163.72 Earth YEARS and Earth revolution period is 365.26 Earth DAYS. Hope I helped.
The farther a planet is from the sun the slower its orbit speed.

In general, the planets that are farther from the Sun move slower, and take longer to go around the Sun. The quantitative relationship (i.e., exactly how much slower) is expressed by Kepler's Third Law.
Mars orbits farther from the sun,tthan Earth does, meand its orbital circumference is longer. Additionally, the farther out an orbiting object is, the slower it travels. So, to complete one orbit, Mars has to travel farther than Earth does and at a slower speed.
Neptune would move the slowest. The orbit speed is related to the distant the planets are to the sun. Farther the planet, slower the pace. Remember, Pluto is no longer a planet.
Saturn is slower because it is farther from the sun. The farther away a planet is from the sun, the slower its orbital speed.
Because the farther away from the sun, the longer it will take to travel around it in an orbit. Also the planets move slower when further away due to less gravitational pull. Believe it or not, there are dwarf planet far out in the oort cloud that take thousands of Earth years for one of there years. If you do not know what the oort cloud is, it is the furthest region, where comets, some asteroids, and a few dwarf planets are found, and at the end of the oort cloud is where the sun's gravitational dominance ends. Oh, and I'm a 14 year old answering this.
Neptune moves more slowly than Earth. The farther a planet is from the Sun, the longer its orbit. But the lesser gravity of the Sun at longer distances means that the planets also do not need to move as rapidly in their orbits. A planet farther from the Sun moves more slowly than one closer to the Sun.
Because it takes longer and slower to go around the sun therefor making it a longer year.
incorrect. The farther away from earth a galaxy is, the faster it is moving.

Mars takes longer to make one orbit of the sun. Its slower, and it also has further to go. Planets orbiting speeds get slower the further you go out.
Jupiter moves slower than earth around the sun because the distance between the them is much farther than earth's distance to the sun. Gravity has a stronger pull on earth because gravity depends on the masses and the distance between the objects. (Sun)---->Earth (Sun)---- - - - - - - ->Jupiter
