Talk:Hour circle

Merge with hour angle?
The article hour angle seems very similar to the hour circle. Should they be merged? Sam-2727 (talk) 22:20, 30 December 2018 (UTC)
 * No. An hour circle is a great circle, while an hour angle is an angle between two great circles. It is useful to differ between these concepts when explaining or defining astronomical terms such as the parallactic angle. Utfor (talk) 04:50, 23 November 2021 (UTC)
