The observer’s meridian arc going from from the north point of the horizon, up through the zenith, and down to the south point of the horizon. The meridian is an important reference as it is the place where an object in the sky (like the stars, sun, or moon) will be “highest” in the sky.

Those include words like asteroids, satellite and zenith, as well as the names of planets and the. Outreach at Yerkes Observatory in Chicago who works on projects making astronomy more accessible.

Otherwise, it will miss the zenith by the same angle as the difference between your location and its declination. It will be at the highest it happens to reach when the local sidereal time is equal to its right ascension, in an event called transitting (for the Pleiades, at 03:47 local sidereal time ).

For almost half a century astrono mers have been able to do this by recording the fall‐off in ab sorption as the star nears the zenith. The closer the star gets to the zenith, the less air its light.

Positional Astronomy: Coordinate systems: the horizontal or "alt-az" system. The altitude (a) of object X is the angular distance along the vertical circle from the horizon to X, measured from -90° at nadir to +90° at zenith. Alternatively, the zenith distance of X is 90° – a. (Some authors use h instead of a.) Any two objects with the same altitude lie on a small circle called a parallel of altitude.
