The mean solar day is 86 400 seconds (SI).
The period of revolution is 365,242 199 mean solar days.
One (1).
Mars has roughly twice the Earth's period of revolution.
Earth's rotation takes exactly one Earth year (definition).
Mercury's period of rotation, or the time it takes to complete one full rotation on its axis, is 58.6 Earth days. Its period of revolution, or the time it takes to orbit the Sun, is about 88 Earth days. This means that one day on Mercury (rotation) is longer than one year on Mercury (revolution).
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.
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.
Jupiter takes about 11.86 Earth years to complete one orbit around the Sun. This is known as its orbital period or revolution.
Venus has the closest period of revolution to Earth, taking approximately 225 Earth days to complete one orbit around the Sun.
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.
