NASA reported that Gemini 4 made 62 revolutions, defined as passes over Cape Kennedy's longitude (Gatland، Kenneth (1976). Manned Spacecraft, Second Revision. New York: Macmillan Publishing Co. ص. 168. ISBN:0-02-542820-9.), the duration of which is longer than an orbit because of the Earth's eastward rotation. This is analogous to the difference between a يوم اقتراني and a توقيت فلكي due to the Earth's revolution around the Sun.
