Out of the inner planets, Mars has the longest orbital period (year), because of two things:
• Mars is farther away from the Sun than the rest of the inner planets. Imagine this; if you are walking around a pole ten feet (three meters) away from it at all times in a path that is in the shape of a circle, and someone else walks around the pole twenty feet (six meters) away from it in a circular shape, you will walk completely around it twice while the other person walks around it once. This is because the other person is further away from the pole than you are, so his path is longer.
• Mars orbits the Sun slower than the rest of the inner planets. This is because, since Mars is further away from the Sun than the rest of the inner planets, it is affected less by the gravitational pull of the Sun.
Mercury has the longest year in revolution among the inner planets, taking about 88 Earth days to complete one orbit around the Sun.
Out of Mercury, Earth, Mars, and Jupiter, Jupiter has the longest year.
The order of the planets by longest year is the normal order (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune). The farther away a planet's orbit is from the Sun, the longer the year.
Pluto has the longest year, if it was still a planet that is, equal to 248.76 Earth years. Since Pluto is no longer considered a planet, the planet with the longest year is Neptune, at 164.8 Earth years per revolution around the Sun.
What inner planet has the shortest year
The longest year on any planet that circles around our sun is on Pluto, which one year on Pluto roughly is 248 Earth years. <><><><><> Since Pluto is no longer considered to be a planet, the role of longest year falls to Neptune, with 168.4 years.
It would have to be Earth, since it is the only inner planet with oceans.
Mars has an orbital period of around 687 days.
