The planet that has a revolutionary period almost 30 times longer than earth Saturn. It takes about 29.45 earth years to complete a revolution.
Saturn.
Mercury
Mercury has the shortest period of revolution around the Sun, at approximately 88 Earth days.
The farther it is from the sun the longer its period of revolution (its "year").
Mars, with a orbital period of around 687 days, almost two Earth years (which would be 730 days).
Each planet's year is determined by its orbital period, which is the time it takes to complete one orbit around the Sun. The further a planet is from the Sun, the longer its orbital period, resulting in a longer year. This is due to the gravitational force of the Sun, which influences the speed and distance at which each planet orbits.
A planets period or revolution, the time taken to orbit its star, is dependant on its mass, the stars mass and the distance between the two. See Kepler's laws of planetary motion for further information.
Based on the fact that Planet A has a greater mean distance from the Sun than Planet B, you can correctly infer that Planet A likely has a longer orbital period than Planet B. This is because planets that are farther from the Sun generally take longer to complete one orbit.
The farther away from the sun, the longer the period of revolution takes.
The distance of a planet from the sun affects its orbital period. Generally, the farther a planet is from the sun, the longer its orbital period will be. This relationship is described by Kepler's third law of planetary motion, which states that the square of a planet's orbital period is directly proportional to the cube of its average distance from the sun.
In our solar system Neptune is the planet with the longest period or year - equal to about 165 Earth years.
Mars, with a orbital period of around 687 days, almost two Earth years (which would be 730 days).
