It goes right round 360 degrees in 24 hours, so 6 hours for 90 degrees, relative to the Sun.
Relative to the distant stars, it takes the Earth about 5 hours, 59 minutes to rotate 90 degrees.
If the Earth rotates 15 degrees/hour, then 7.5 degrees is half of 15, so it takes half an hour or 30 minutes.
165 (Earth) years.
A full rotation of Earth is considered one day if only the planet is observed, therefore the Earth will rotate 360 degrees in a day. If the rotation of the Earth is taken into account with the orbit around the sun, the Earth will rotate just under 361 degrees per day.
The Moon takes about 27.3 days to complete one full rotation on its axis, which is also the same amount of time it takes to orbit the Earth. This synchronous rotation means that the same side of the Moon always faces Earth. Consequently, this phenomenon is known as tidal locking.
Callisto takes about 16.7 Earth days to complete one full rotation on its axis.
Rotate 360 degrees
It goes right round 360 degrees in 24 hours, so 6 hours for 90 degrees, relative to the Sun. Relative to the distant stars, it takes the Earth about 5 hours, 59 minutes to rotate 90 degrees.
The Earth rotates one full rotation - 360 degrees - in 23 hours and 56 minutes.

It takes 23.9345 hours. The axis is tilted by 23.44 degrees.

The Earth takes approximately 24 hours to complete a full 360-degree rotation on its axis. Therefore, to rotate 90 degrees, it takes about 6 hours. This is because 90 degrees is one-quarter of a full rotation, so the time is divided accordingly.
