The mean solar day is 86 400 seconds (SI).

One (1).
Mars has roughly twice the Earth's period of revolution.
Earth's rotation takes exactly one Earth year (definition).
27.32 days
The process is called 'revolution'. The period of time the Earth takes to complete one entire revolution is called 'one year'.
Saturn has a period of revolution that is approximately twice as long as Earth's. While Earth takes about 365 days to complete one revolution around the Sun, Saturn takes roughly 29.5 Earth years to complete its orbit.
Jupiter has a period revolution (or orbital period) of 4331 Earth days.
Venus' period of rotation is 243 Earth days. Its period of revolution is 224. 7 Earth days. The revolution period is the length of a year in Earth days on Venus. This planet is a terrestrial planet.
Earth
From the point of view of a person on earth, the moon's period of rotation on its axis and revolution around earth are both 27.32 days. From the point of view of a person on the moon, the period of rotation on its axis and revolution around earth are both 27.32 [earth] days, and the period of revolution around the sun averages 365.24 earth days.
