The ecliptic is the path the sun, moon, and planets take across the sky as seen from Earth. It defines the plane of the Earth's orbit around the sun. The name "ecliptic" comes from the fact that ...

The trapezoids were created by plotting graphs of Jupiter's apparent velocity ... to work out Jupiter's displacement along the ecliptic, the path the sun appears to follow across a background ...

The ecliptic is inclined 23.5° to the celestial equator because this is the amount Earth’s rotation axis is tilted relative to its orbit. The Moon follows generally the same path, but with some ...

But because the angle of the ecliptic - the path the planets, sun and moon follow - is so shallow in the western sky in November, Mercury nearly scrapes the horizon. Venus does only a little better.
