An astronomer would determine an ecliptic plane's location on the celestial sphere by
A)drawing a circle around the object to the surface of the Earth to determine the point where the circle pierces the sphere and represents the object's position.
B)drawing a line from the object to the center of the Earth to determine the point where the line pierces the sphere and represents the object's position.
C)using GPS technology to determine the point where the line pierces the sphere and represents the object's position.
D)drawing a line from the object to the center of the Earth.

Quizplus · Accepted Answer

An astronomer would draw a line from the object to the center of the Earth to determine the point where the line pierces the celestial sphere and represents the object's position. The intersection of this line with the celestial sphere indicates the object's position on the sphere. The ecliptic plane is the imaginary plane that represents the path of the sun across the sky as observed from Earth, and it is determined by the location of the Earth in its orbit around the sun. So, the astronomer will locate the ecliptic plane by determining the positions of the sun on the celestial sphere at different times of the year.
