Learn how to use altitude (elevation) and azimuth angles to locate any object in the sky, such as stars, planets, satellites, the Sun, or the Moon.

Horizontal coordinates use a celestial sphere centered on the observer. Azimuth is measured eastward from the north point (sometimes from the south point) of the horizon; altitude is the angle above the …

Altitude and azimuth, in astronomy, gunnery, navigation, and other fields, two coordinates describing the position of an object above Earth. Altitude in this sense is expressed as angular elevation (up to 90°) …

Azimuth measures the position of a point along a horizon, whereas elevation measures the distance of a point above sea level or an equivalent datum on a planetary surface.

Using a magnetic compass and a ruler to measure altitude and azimuth will allow your students to accurately observe and record the position of any object in the sky whether near or far!

In astronomy, gunnery, navigation, and other fields, [altitude and azimuth are] two coordinates describing the position of an object above the Earth. Altitude in this sense is expressed as angular …

These terms are based on the location of the observer at any given time. It is important to remember that over the course of long observing session the stars position will change. We can measure how …

General features The horizontal coordinate system is fixed to a location on Earth, not the stars. Therefore, the altitude and azimuth of an object in the sky changes with time, as the object appears …

Explore the concepts of altitude and azimuth in astronomy, their etymology, detailed definitions, and how they are used to locate celestial objects. Understand the importance of these coordinates in various …

Altitude and azimuth are the two coordinates used to locate an object in the horizontal coordinate system. Altitude measures the angle of an object above or below the local horizon, while azimuth …
