Question

question 6 1 pts what is the celestial sphere? the celestial sphere represents a belief in an earth - centered universe, and hence is no longer considered to have any use. the celestial sphere is a representation of how the entire sky looks as seen from earth. the celestial sphere is a model that shows the true locations in space of the sun and a few thousand of the nearest stars. the celestial sphere is a model of how the stars are arranged in the sky relative to our sun, which is in the middle of the sphere. the celestial sphere is another name for the sun.

Explanation:

• Option 1: The celestial sphere still has uses (e.g., in astronomy for positional astronomy), so this is wrong.
• Option 2: The celestial sphere is a conceptual model where the sky is represented as a sphere around Earth, showing how the sky appears from Earth. This matches the definition.
• Option 3: It doesn't show true spatial locations but apparent positions from Earth, so wrong.
• Option 4: The Sun is not at the middle in terms of true space (it's a geocentric - apparent - model), so wrong.
• Option 5: The celestial sphere is not the Sun, so wrong.

Answer:

B. The celestial sphere is a representation of how the entire sky looks as seen from Earth.
