The term for a unit of angle used in both astronomy and navigation is what?

The term for a unit of angle used in both astronomy and navigation is commonly referred to as a minute. In this context, a minute is a subdivision of a degree, where each degree is divided into 60 minutes, and each minute can further be divided into 60 seconds. This system is particularly important in both fields, as precise measurements are crucial for determining positions in the sky or on the Earth.

In astronomy, for instance, celestial objects are often located using coordinates that involve degrees, minutes, and seconds. Similarly, in navigation, especially in marine or aerial contexts, these units help in pinpointing locations accurately on charts and maps. The accuracy provided by using minutes and seconds allows navigators to account for the curvature of the Earth or the vastness of space.
