Azimuth is the angle, typically using true north as zero degrees to an object from viewers location. An altitude (if expressed as an elevation angle from the viewer) provides a line of sight to an object in space. If you were standing at a point and facing true north and there was an airplane flying at 20,000 ft and you knew the elevation angle you could compute the range and have an (X,Y,Z) location for the object.

What Azimuth and altitude are used to describe the star?
Azimuth is the horizontal angular distance measured clockwise from true north, while altitude is the vertical angular distance above the horizon. Together, these coordinates help locate a star's position in the sky.
Does the rotation of the earth affect the azimuth and altitude?
Yes, the rotation of the Earth affects the azimuth and altitude of celestial objects, as they appear to move across the sky due to the Earth's rotation. The azimuth (horizontal direction) changes as objects rise in the east and set in the west, while the altitude (vertical angle) changes as objects rise higher in the sky and then descend.
Why must two coordinates azimuth and altitude be given to specify the location of an object in the night sky?
Azimuth and altitude are essential for specifying the location of an object in the night sky because they provide a two-dimensional coordinate system based on an observer's local horizon. Azimuth indicates the compass direction (0° to 360°) from which an object is observed, while altitude measures the object's angle above the horizon (0° at the horizon to 90° at the zenith). Together, these coordinates allow for precise positioning of celestial objects relative to the observer's viewpoint on Earth. Without both coordinates, the object's location would be ambiguous.
What is the Azimuth and the altitude if the latitude is 20 degree north the right ascension is 11 hour and the declination is -10 degree?
That will depend on the time of day. The point in the sky at that RA and declination will revolve all the way around any observer at that latitude in roughly 24 hours. The highest it will ever get in his sky will be when it transits due south of him. At that moment, its azimuth will be 180° and its elevation will be 60° above the southern horizon.
What is a back azimuth?
A BACK AZIMUTH IS A PROJECTION OF THE AZIMUTH FROM THE ORIGIN TO THE OPPOSITE SIDE OF THE AZIMUTH CIRCLE. i.e. THERE ARE 360 DEGREES IN AN AZIMUTH CIRCLE, THUS THE OPPOSITE DIRECTION IS 180 DEGREES.
How could the altitude and azimuth be important?
There are a number of ways to describe locations or positions. One of these is to describe the direction toward an object in degrees; this is the "azimuth". For objects in the sky, we must also know the angular elevation above the horizon, or "altitude angle". This is usually shortened to "altitude". By specifying the azimuth angle and altitude angle, we can describe precisely the direction of any object in the sky.
What is the azimuth and altitude of Sagittarius?
The azimuth and altitude of Sagittarius depend where you are on Earth and the date and time. The altitude can be anything form 0-90, and the azimuth 0-180.
What will be the azimuth and altitude of a star which setting directly in the northwest?
Azimuth = 315° (True) Altitude = 0
What Azimuth and altitude are used to describe the star?
Azimuth is the horizontal angular distance measured clockwise from true north, while altitude is the vertical angular distance above the horizon. Together, these coordinates help locate a star's position in the sky.
Does the rotation of the earth affect azimuth and altitude?
The variation of the apparent azimuth and altitude of everything we see in the sky is the result of Earth's rotation.
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.
What is the azimuth and altitude of the star Betelgeuse?
As of 2021, Betelgeuse has an azimuth of around 225 degrees and an altitude of about 27 degrees when observed from the northern hemisphere. These values will change throughout the night and over the course of the year due to the Earth's rotation and orbit.
Does the rotation of the earth affect the azimuth and altitude?
Yes, the rotation of the Earth affects the azimuth and altitude of celestial objects, as they appear to move across the sky due to the Earth's rotation. The azimuth (horizontal direction) changes as objects rise in the east and set in the west, while the altitude (vertical angle) changes as objects rise higher in the sky and then descend.
What are the altitude and azimuth of a star that is now setting due west?
The point on the horizon that is due west has an altitude of zero and an azimuth of 270 degrees.

What are the types of sundials?
The two types of sundials are altitude and azimuth sundials.
What are three reference points used to describe a star or planet's location in relation to a person's position?
This is probably about the "horizon coordinate system". Or, it's sometimes called the horizontal coordinate system. The system uses "altitude" and "azimuth" as coordinates. The azimuth is normally measured from due North as zero. So, that's the "three reference points", probably. Altitude is the angular height of a star above the horizon. Azimuth is the angle of a star measured along the horizon, from the pole.
