Saturn.
The answer is Mercury.
Mars, with a orbital period of around 687 days, almost two Earth years (which would be 730 days).
Almost exactly 88 Earth days.
Most recently that would be Pluto. But Pluto was not the first object called a planet to be later demoted. The asteroid Ceres was known as a planet for a longer period of time than Pluto was.
Planet A's Revolution period is longer.
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.
The answer is Mercury.
Mercury
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).
Mars, with a orbital period of around 687 days, almost two Earth years (which would be 730 days).
The farther away from the sun, the longer the period of revolution takes.
In our solar system Neptune is the planet with the longest period or year - equal to about 165 Earth years.
Almost exactly 88 Earth days.
Most recently that would be Pluto. But Pluto was not the first object called a planet to be later demoted. The asteroid Ceres was known as a planet for a longer period of time than Pluto was.
Planet A's Revolution period is longer.
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.
