WebThe ecliptic is the Sun ’s path through the starry background of the sky. The Moon and planets follow a similar track. The Sun’s position relative to the stars is revealed during the darkness of a total solar eclipse.

A conjunction is when two astronomical objects appear close to each other in the sky. The bodies involved can be the Sun, the Moon, a planet, or a star. Although the objects appear to be close, this is an illusion caused by perspective. During a conjunction, Earth forms an (almost) straight line with the two other bodies ...
In astronomy, the ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations of Solar System objects. Because most planets (except Mercury) and many small Solar System bodies have orbits with only slight inclinations to the ecliptic, using it as the fundamental plane is convenient. The system's origin ca…
