As an observer on a ship at sea at which latitude does the north star appear closest to the horizon?
I'm assuming that you mean "How far from the NCP is something whose declination is 50 degrees N?" In that case, the best way to visualize it is by looking at a globe of earth. The north pole is at 90 degrees N latitude. Something that's 50 degrees N latitude is therefore 40 degrees BELOW the north pole (the UK fits this description). Likewise, something with a declination of 50 degrees N is 40 degrees away from the NCP.

What is the angle of the celestial north pole above the horizon in Frankfurt Germany?
The altitude of the celestial north pole above the northern horizon is exactlythe observer's north latitude on the earth. The center of Frankfurt is very closeto 50° North latitude.
Why does the number of circumpolar constellations depend on the latitude of the observer?
As an observer moves away from the equator, towards the north or south pole, there are more constellations that the rotation of the earth does not ever block from his or her view throughout one full rotation.
Why is it that ships disappear over the horizon?
Ships appear to disappear over the horizon due to the curvature of the Earth. As a ship moves away from an observer, it eventually reaches a point where the curvature of the Earth blocks the line of sight between the observer and the ship, making it seem as though the ship has disappeared.
What is the frame of reference for the sunset?
The frame of reference for the sunset is typically the observer's position on Earth. The changing position of the Earth as it rotates on its axis causes the sun to appear to set below the horizon.
What is a circumpolar contellation?
A circumpolar constellation is a constellation that appears to move around the celestial pole without ever setting below the horizon from a specific location on Earth. These constellations are always visible in the night sky throughout the year in the northern or southern hemisphere, depending on the observer's latitude.
To an observer on a ship at sea at which latitude does north star appear closest to the horizon?
The North Star (Polaris) appears closest to the horizon at the Earth's equator (0° latitude) because as you move away from the equator towards the poles, the angle of Polaris above the horizon increases. At the North Pole (90° latitude), Polaris is directly overhead.
How are the altitude of polaris and latitude of an observer related?
The altitude of Polaris and the latitude of an observer are directly related. The altitude of Polaris in the sky is approximately equal to the observer's latitude in the Northern Hemisphere. The higher the latitude, the higher Polaris will appear in the sky.
How is the altitude of the North Celestial Pole above the northern horizon related to the observer's latitude?
The altitude of the North Celestial Pole above the northern horizon is equal to the observer's latitude. This means that the higher the observer's latitude, the higher the North Celestial Pole will appear in the sky. For example, an observer at a latitude of 45 degrees will see the North Celestial Pole 45 degrees above the northern horizon.
Where would Polaris appear to an observer at the equator?
On the horizon
What is the point to an observer the earth and sky appear to meet?
The horizon.
When does the moon appear largest in the sky?
When its closest to the horizon.
Is this statement true or false the horizon is the point where to an observer the earth and sky appear to meet?
True. The horizon is the line where the Earth's surface and the sky seem to meet from the perspective of an observer. It is influenced by the observer's height and the curvature of the Earth.
What is the angle of the celestial north pole above the horizon in Frankfurt Germany?
The altitude of the celestial north pole above the northern horizon is exactlythe observer's north latitude on the earth. The center of Frankfurt is very closeto 50° North latitude.
What is most likely not to appear on a map out of compass rose legend horizon latitude lines scale?
Lines of latitude do not appear on all types of maps, The other parts do appear on most maps.
Is it true The horizon is the point where to an observer the earth and sky appear to meet?
Yes, that statement is true. The horizon is the line where the Earth's surface and the sky seem to converge from an observer's viewpoint. This line is influenced by the observer's elevation and the curvature of the Earth, giving the impression of a meeting point between land and sky. However, in reality, the Earth is round, and the horizon is simply the limit of what we can see.
What rises in the east and sets in the west for an observer in New York?
Most natural celestial objects do this; exceptions would be any fixed star that is 'circumpolar'-- they are close enough to the celestial poles that they never appear to dip below the observer's horizon. Which stars are circumpolar depends on the latitude of the observer.
Why does the number of circumpolar constellations depend on the latitude of the observer?
As an observer moves away from the equator, towards the north or south pole, there are more constellations that the rotation of the earth does not ever block from his or her view throughout one full rotation.
