The main object of the astronomer to obtain A. Astronomical latitude B. Astronomical longitude C. Astronomical bearing D. All of these

The main object of the astronomer is to obtain all of these. Astronomical latitude, astronomical longitude, and astronomical bearing are all important measurements that astronomers use to track the movement of celestial objects.

• Astronomical latitude is the angular distance north or south of the celestial equator. It is measured in degrees, minutes, and seconds.
• Astronomical longitude is the angular distance east or west of the prime meridian. It is also measured in degrees, minutes, and seconds.
• Astronomical bearing is the direction of a celestial object from the observer’s position. It is measured in degrees, minutes, and seconds from north, east, south, or west.

Astronomers use these measurements to track the movement of stars, planets, and other celestial objects. They also use these measurements to calculate the positions of these objects in the sky. This information is used in a variety of applications, such as navigation, astronomy, and astrology.
