Kiertoaikaa
Kiertoaika, translated as orbital or cycle time in Finnish, is the time it takes for an object to complete one revolution or cycle relative to a reference point. The term is used in different fields, most notably astronomy to describe orbital periods, and in engineering and production to denote a cycle time or throughput interval. The concept is always measured as a duration from one completing event to the next identical event.
In astronomy, kiertoaika refers to the orbital period of a body around a central body, such as
In engineering and production, kiertoaika describes the cycle time—the time required to complete one cycle of
Etymologically, kiertoaika comes from kiertää, “to revolve,” and aika, “time.” See also orbital period, synodic period,
