What is the angular radius of the small circle Polaris traces around the NCP over 24 hours?
Answer
About 0.7 degrees
The star exhibits a very small diurnal path mirroring Earth's rotation, tracing a circle with an angular radius equal to its current separation from the true pole, which is about 0.7 degrees.
