A year.
Round its own axis, one day; round the Sun, one year.
27.32 days
Earth's period of revolution, or orbital period, is the time it takes for Earth to complete one orbit around the Sun. It is approximately 365.25 days. This orbital period is the basis for our calendar year.
The period of a planet's revolution is the time that it takes to complete one revolution around its axis of rotation relative to the background stars (also known as rotation period).
period rotation: 1 rotation of the earth(1 day) period revolution: 1 year around the sun
The process is called 'revolution'. The period of time the Earth takes to complete one entire revolution is called 'one year'.
The period of revolution or orbital revolution. For Earth, this is one year.
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).
The period of rotation is the time it takes for one full revolution. Since the object completes 15 revolutions in 40 seconds, the time for one revolution is obtained by dividing 40 seconds by 15, which gives a period of rotation of approximately 2.67 seconds per revolution.
It takes Mercury 88 Earth days to make one full orbit (or revolution) around the sun.
The Moon's revolution period around the Earth is approximately 27.3 days. This period is known as the sidereal month, and it is the time it takes for the Moon to complete one orbit around the Earth with respect to the fixed stars.
Venus has a revolution period of about 225 Earth days. This is the time it takes for Venus to complete one orbit around the Sun.
