Assuming you mean one rotation on its axis, it takes approximately 24 hours. If by some chance you mean a rotation around the sun (called an orbit) that takes approximately 365 days.
It takes the earth one year to make one rotation around the Sun!
1 rotation of the earth around it's axis is one day. 1 rotation around the sun is one year.
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.
It Takes One Day for the earth to rotate on its axis.
24 hours
It takes one year.
One revolution of the Earth on it's axis takes 24 hours. One rotation of the Earth around the sun takes 365.25 days.
One revolution of the Earth on it's axis takes 24 hours. One rotation of the Earth around the sun takes 365.25 days.
Roughly 4 minutes less than 24 hours.
One day (or one rotation around its axis) takes 1407.6 Earth hours.
The "day" on Mars, the time it takes for one complete rotation, is about 24.62 Earth hours.
