Question

Our earth rotates around its ___________ at a certain speed ​

Answer 1

Answer:

The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.

Answer 2

Answer:

Our earth rotates around it's Axis at a certain speed. Facts explained below.

Explanation:

1. The rotation of the planet Earth around its own axis and variations in the orientation of the rotation axis in space are referred to as Earth's rotation or Earth's spin. Earth rotates progradely in an easterly direction. Earth rotates against the direction of the northern polar star Polaris.
2. The Northern Hemisphere's North Pole, sometimes referred to as the Geographic North Pole or Terrestrial North Pole, is where the Earth's axis of rotation and surface meet. The North Magnetic Pole of the Earth is distinct from this place. The other location where the axis of rotation of Earth crosses the surface is the South Pole, which is located in Antarctica.
3. The Earth revolves once every 24 hours or so in relation to the Sun, but only once every 23 hours, 56 minutes, and 4 seconds in relation to other far-off stars (see below). A day used to be shorter because the Earth's rotation was slower back then. This is caused by the tidal influences the Moon has on the rotation of the Earth. Atomic clocks reveal that a modern day is longer than one from a century ago by around 1.7 milliseconds,[1] which gradually accelerates the rate at which UTC is modified by leap seconds. The duration of a day has increased by around 2.3 milliseconds every century since the eighth century BCE, according to an analysis of historical astronomical records, but this tendency is slowing down.
