# How to roughly calculate the angular velocity of the Earth’s rotation around the Sun?

To approximately calculate the angular velocity of the Earth’s rotation around the Sun, it is necessary to divide 2n by the time of one complete revolution (day), expressed in seconds.

This is a value that is equal to the ratio of the angle of the body to the length of time spent on this rotation. We can say that this is the rate of change in the angle of the body over a period of time. It is expressed in radians per second, and has a constant value for all points.

As it turned out, it takes 23 hours 56 minutes 4.09053 seconds to complete a revolution of our planet around its axis, or, more simply, one sidereal day.

Since the earth’s revolution is 360 degrees or 2π (2 * 3.14 = 6.28), and the time of this revolution is 86344 seconds, the angular velocity of the Earth’s rotation around its axis is approximately equal to 7.26851851851-5s-1.
