It takes one year.
Moon approximately take 27.3 days to complete one rotation around earth
That is how long it takes for the earth to fully complete a rotation around the sun
The time it takes for one rotation depends on the object rotating. For example, it takes Earth approximately 24 hours to complete one rotation around its axis, while the Moon takes about 27.3 days to complete one rotation.
Because that is how long it takes for the earth to complete a full orbit (rotation) around the sun
Mercury takes about 59 Earth days to complete one rotation on its axis. This is longer than its orbital period around the sun, which is about 88 Earth days.
Mercury is 58.646 earth days.
1 rotation of the earth around it's axis is one day. 1 rotation around the sun is one year.
The earth rotates once ever 23 hours 56 minutes and 4 seconds.
One complete rotation around the Sun, or one year, is about 365.25 days.
A new day begins. Or the Earth has rotated once around it's axis (Not actually true as one complete rotation takes 23h 56m 4.100s)
It takes Mercury about 59 Earth days to complete one full rotation on its axis. This means that a day on Mercury (one full rotation) is equivalent to 59 Earth days.
The "day" on Mars, the time it takes for one complete rotation, is about 24.62 Earth hours.
