How is azimuth defined in astronomy?

• A. The distance from an observer to a celestial object
• B. The angle between the north point and a celestial object
• C. The height of a celestial body above the horizon
• D. The circular path of a planet's rotation

Answer: (B)

Azimuth is defined as the angle measured in the horizontal plane from a reference direction, typically true north, to the direction of a celestial object. This angle helps locate objects in the sky by providing a direction to look. The value is usually given in degrees, ranging from 0° to 360°, with 0° corresponding to north. Understanding this definition is crucial for navigation, astronomy, and various applications where precise measurements of celestial positions are needed. The other options refer to different concepts; for instance, distance relates to range rather than direction, height pertains to the elevation above the horizon, and circular paths describe motion rather than position.
