The "ecliptic".
In truth, the Sun doesn't move; the apparent motion of the Sun across the sky is caused by the Earth spinning, and the apparent motion of the Sun across the "celestial sphere" is caused by the Earth orbiting the Sun.
But the plane of the Earth's orbit around the Sun is what causes the apparent motion of the Sun across the celestial sphere, so the "ecliptic" is actually the plane of the Earth's orbit.
What else can I help you with?
What is the imaginary sphere on which all objects in the sky seem to be located?
The imaginary sphere is called the celestial sphere. It is used in astronomy to track the apparent movements of celestial objects as if they were projected onto the inside of a sphere surrounding the Earth.
What celestial line is a product of the Earth's rotation?
The celestial line that is a product of Earth's rotation is the celestial equator. It is an imaginary line located above Earth's equator and is created as a result of Earth's rotation on its axis. It divides the celestial sphere into northern and southern hemispheres.
Why the Doppler shift tells us only about the motion directly along the line of sight between a light source and an observer but not about motion across the celestial sphere?
The Doppler shift only measures the component of motion directly towards or away from the observer. Motion across the celestial sphere does not impact the frequency of light perceived by the observer along the line of sight. This is because the Doppler effect is only sensitive to changes in the relative velocity between the source and observer along the line connecting them.
What celestial line is created by Earth's revolution around the sun?
The celestial line created by Earth's revolution around the sun is called the ecliptic. This is the apparent path that the sun appears to follow across the sky over the course of a year.
What information can be obtained from a celestial sphere map?
A celestial sphere map provides information about the positions of stars and constellations in the night sky as seen from a specific location on Earth. It can help astronomers and stargazers identify and locate celestial objects, track their movements, and navigate the night sky.

The celestial line that is a product of Earth's rotation is the celestial equator. It is an imaginary line located above Earth's equator and is created as a result of Earth's rotation on its axis. It divides the celestial sphere into northern and southern hemispheres.
What is the imaginary line in the heavens that runs around the earth the earth midway between the celestial poles?
The celestial equator is the imaginary line in the heavens that runs around the Earth midway between the celestial poles. It is an extension of Earth's equator onto the celestial sphere and divides the sky into northern and southern hemispheres.
The planets and the moon never stray very far from what imaginary line on the celestial sphere?
that is called the orbit. that's where they revolve.

What is a line on a sphere?
It's a line... on a sphere...

What is daimeter?
Daimeter is not a word, but diameter is basically a straight line that passes through the center of a sphere. This line begins at the perimeter and passes completely across the circle.
What do we call the imaginary extension of earth's equator into space?
The imaginary extension of Earth's equator into space is called the celestial equator. It is an imaginary line in the sky above the Earth's equator, dividing the celestial sphere into northern and southern hemispheres.
What information can be obtained from a celestial sphere map?
A celestial sphere map provides information about the positions of stars and constellations in the night sky as seen from a specific location on Earth. It can help astronomers and stargazers identify and locate celestial objects, track their movements, and navigate the night sky.
What is the intersection of a line and a sphere is called?
Two points. These may coincide if the line is a tangent to the sphere.
What is the difference between the celestial equator and the horizon?
The celestial equator is an imaginary line in the sky that represents the projection of Earth's equator onto the celestial sphere. It divides the sky into northern and southern hemispheres. The horizon, on the other hand, is the line where the sky meets the Earth's surface when viewed from a specific location, forming the boundary between the visible sky and the ground.
