How do you determine the altitude at which the celestial equator cuts the meridian?
The altitude at which the celestial equator intersects your local meridian is the complementof your latitude, i.e. the difference between your latitude and 90 degrees.On the equator: Your latitude is zero. (90 - 0) = 90. Celestial equator passes overhead.At the pole: Your latitude is 90. (90 - 90) = 0. Celestial equator coincides with the horizon.In New Orleans, Louisiana, or Durban, South Africa: Your latitude is 30. (90 - 30) = 60.Celestial equator intersects local meridian at 60 degrees above the horizon.
What latitude on earth is a celestial pole 45 above the horizon'?
At 45 degrees north latitude, the north celestial pole appears 45 degrees above the northern horizon. At 45 degrees south latitude, the south celestial pole appears 45 degrees above the southern horizon.
Latitude is based on the celestial observation of?
Latitude is not based on any celestial observation, but rather the geographical location - how far north or south the place is - with respect to the equatorial circle. You could say it is based on terrestrial observation, if you like.
How far from zenith is the celestial equator when it crosses the celestial?
The angle between the celestial equator and your personal zenith is equal to the latitude of your location. (Whether it's north or south latitude doesn't matter, and neither does your longitude or the time of day or night where you are.)
What were three methods of determining latitude and which one was the most accurate?
The latitude and longitude of that point is known as the celestial body's geographic ... (Two other common methods for determining one's position using celestial ... The sextant and octant are most accurate because they measure angles.
What is the star latitude and star declination?
Celestial coordinates. -- The star's latitude on the celestial sphere is the same as the Earth latitude that it seems to follow on its way aroujnd the sky. On the celestial sphere, the latitude is called "declination", and is expressed in degrees. -- The star's longitude on the celestial sphere is its angle, measured westward, from the point in the sky called the Vernal Equinox ... the point where the sun appears to cross the celestial equator in March. On the celestial sphere, the star's longitude is called "Right Ascension", and it's expressed in hours. That certainly seems confusing, but an "hour of Right Ascension" just means 15 degrees of celestial longitude. So, as the sky turns, the point directly over your head moves through the stars by 1 hour of Right Ascension every hour.

What system of navigation in which a navigator observes celestial bodies to measure latitude?
Celestial navigation.
What do astronomers call latitude and longitude?
When astronomers are working with geographic maps, they call latitude "latitude"and longitude "longitude".When they're working with celestial maps, they refer to the analogous celestial coordinatesas "Declination" and "Right Ascension".
What system is the celestial coordinate system most similar to?
The celestial coordinate system is exactly analogous to the terrestrial positioning system based on latitude and longitude. Terrestrial latitude ---> celestial 'declination'. Terrestrial longitude ---> celestial 'right ascension', where one 'hour' = 15 degrees.
Why don't we use latitude and longitude for celestial coordinates?
We more or less do, we just call them declination and right ascension instead. The two concepts are mathematically equivalent.
What latitude on earth is a celestial pole 45 above the horizon'?
At 45 degrees north latitude, the north celestial pole appears 45 degrees above the northern horizon. At 45 degrees south latitude, the south celestial pole appears 45 degrees above the southern horizon.
What never sets at your latitude?
Any sky object within (your latitude) degrees of the north celestial pole.

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.
