What is the correct term Zenith is the angle between an object and the horizon?
The correct term is "zenith angle." It is the angle measured from the vertical direction (zenith) to the point directly above an observer. It is used to determine the position of an object in the sky relative to the observer's horizon.
What are the altitude and azimuth of a star halfway between the horizon and zenith to the due east?
An object seen halfway between the horizon and the zenith has an altitude of 45 degrees.An object seen due east of the observer has an azimuth of 90 degrees.
Define true zenith distance n meridional zenith distance?
The true zenith distance is the angular distance between a celestial object and the observer's zenith, measured along the observer's vertical circle. The meridional zenith distance is the true zenith distance measured along the observer's meridian.
Can you define altitude of a celestial body?
Altitude of a celestial body is the angular distance between the horizon and the body when viewed from a specific location on Earth. It is measured in degrees and ranges from 0° at the horizon to 90° at the zenith, directly overhead.
What is the great circle passing through the south point on the horizon the zenith and the north point on the horizon is called?
The great circle passing through these points is called the meridian. It is an imaginary line that runs from the north celestial pole to the south celestial pole, passing through the zenith (overhead point) and intersecting the horizon at the north and south points.
