what is the celestial sphere?

Answer 1

It is the spherical projection of all the visible stars and constellations, using coordinates much like latitude and longitude to locate all the stellar and planetary objects.

Imagine you were standing at the center of a large sphere at the center. The sphere is coated black as the night sky and painted upon the inside surface of the sphere is the precise location of every star and planet (and Moon). That's what you would see -- a night sky map.

Answer 2

The celestial sphere is an imaginary expansion of the earth's Globe, in which longitude and latitude is plotted to locate celestial bodies. It is very usefull for navigation and astronomy. The longitude is measured in hour angles in units of hour minutes and seconds in the right of ascenssion; the latitude is measured in degrees . The North Pole is called Zenith and the South Pole is called Nadir and measurements are taken relative to the Poles.

Answer 3

It's an old, wrong idea. It's the imagined sphere with Earth at the center, which has all the stars on it and which rotates around us daily.

We now know that the stars are all at varying distances away, hanging in emptiness rather than fixed upon a ceiling of some kind.

Answer 4

It's the apparent sphere of stars, galaxies etc that you see when you look up at night.
