WebOct 6, 2024 · AIUI, the declination of astronomical object refers to the latitude on Earth where it is at the celestial zenith - i.e., straight up, along the line from the Earth's center and surface at such zenith, so this point on Earth moves along the latitude line, East to West. What is confusing me is this Wikipedia article about Lunar Standstill. WebBoth altitude and elevation are measures of the height of a point relative to some datum. The differences are in how they are derived and what they are normally used for. Altitude is typically only used to describe the height of an aircraft in flight. It is a barometric measurement expressed relative to the height of a runway or mean sea level in a given …

http://www.seasky.org/astronomy/astronomy-glossary.html Just as the geographic coordinate system uses latitude and longitude to define any location on Earth, the horizontal coordinate system provides altitude and azimuth angles to locate objects in the sky. 1. Altitude or elevation: The angle the object makes with the horizon. Objects that seem to touch the horizon … See more Based on two coordinates, altitude and azimuth, the horizontal coordinate system provides the general direction in which to find a celestial object. Although the distance of the visible planets, stars, and galaxies differs by … See more Imagine the sky as a dome towering above you, its edges resting on the horizon. This is the backdrop the horizontal coordinate system uses to map the sky and describe the positions of its … See more The horizontal coordinate system owes its name to the fact that it is based upon the observer's horizon. As the horizon's limits – and, therefore, the portion of the sky you see – depends on your location, an object's altitude and … See more The horizontal line separating the two hemispheres is called the celestial horizon. It is a continuation into space of the imaginary plane created between you and the horizon … See more solpadeine side effects snorted
