...was used in some primitive calendars (until calendars became more accurate). We still divide a circle into 360 degrees, each degree into 60 minutes, and each minute into 60 seconds. The number 360 is wonderful because it is evenly divisible by so many smaller numbers. You can divide... | |

...separation between the components of a double star is given in seconds or minutes of arc. A full circle is divided into 360 degrees, each degree into 60 minutes and each minute into 60 seconds, so that one second of arc is a very small angle indeed. It is worth remembering that the distance between... | |
