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.
Does The celestial equator always pass directly overhead?
If you are standing at the north or south pole, then the celestial equator coincides with your horizon. At other latitudes, half of the celestial equator is above the horizon, and half is below it.
What sphere of earth is made of all the rock above and below earths surface?
Geosphere
What sphere of earth is made of all rock above and below earth surface?
Geosphere
What layer is directly below the lithosphere?
It is the asthenosphere.
What does nadir mean?
Answer1. an extreme state of adversity; lowest point of anything2. the point below the observer that is directly opposite the zenith on the imaginary sphere against which celestial bodies appear to be projected
Where does the word nadir originate from?
The word "nadir" comes from Arabic "nadir," meaning "opposite." It was borrowed into English from Medieval Latin in the 14th century. In astronomy, nadir is the point on the celestial sphere opposite the zenith and directly below the observer.
What is a globe of the night sky called?
Understanding that there is no physical thing there, the term "Celestial Sphere" is often used. Early astronomers believed that the "celestial sphere" was a solid crystal sphere, and that the stars were embedded in the crystal. Below the crystal, the Sun, the Moon and five "wanderers", or "planeta" passed over the ground as the Celestial Sphere circled high overhead.

What is the angle of declination and how do you use it?
An angle of declination is relevant when an observer is at a higher altitude than the object being observed. It is the angle made by the line of sight with the horizontal. Suppose this is angle x. Then if the altitude of the observer is known to be h, then line-of-sight distance to the object is h*sin(x). The object is h*tan(x) from the point below the observer at the level of the object.Conversely, if the line-of-sight distance from the object to the observer or the horizontal distance to the point directly below the observer is known, it is possible to calculate the height of the observer.
What axis of the sphere below is 16 units in length What is the surface area of the sphere?
The answer is given below.
Why an observer in the southern hemisphere cannot see the star polaris?
Polaris is always below the horizon, to an observer in the Southern Hemisphere.
The axis of the sphere below is 12 units in length what is the surface of the sphere?
144pi units2
The axis of the sphere below is 12 units in length What is the surface area of the sphere?
144pi units squared
What is the zenith and how does the definition of the horizon relate to it?
The zenith is the direction directly above the observer. The astronomical horizon is the plane that is perpendicular to that direction, i.e. horizontal. The "true horizon", however, is the cone from the observer to the point on the earth, below which you can not "see over", so it is a small amount lower in angle. In practice, the two horizons can be considered to be the same, because the height of the observer is often small in comparision to the diameter of the earth, unless the observer is standing on a tall point, such as a mountain.
What state is directly below Minnesota?
