Question 1657Navigation General

The correct answer is A) diurnal circle. The path of a celestial body during its daily apparent revolution around the Earth is called its diurnal circle. This is because the daily motion of a celestial body, as observed from the Earth's surface, appears to be a circular path. The diurnal circle is the apparent daily arc described by a celestial body as the Earth rotates on its axis. The other options are incorrect because: B) ecliptic is the apparent annual path of the Sun against the background stars. C) circle of position is a circle on the celestial sphere that represents all points of equal altitude for a particular celestial body. D) altitude circle is a great circle on the celestial sphere that passes through the zenith and the celestial body and is perpendicular to the horizon.
