The ecliptic is the region of sky (region of the celestial sphere) through which the Sun appears to move over the course of a year.
Ecliptic longitude (celestial longitude) is one of the co-ordinates which can be used to define the location of an astronomical object on the celestial sphere in ecliptic coordinates.

Although Cetus is not considered part of the zodiac, the ecliptic passes close to its constellation boundary, and thus the planets may be seen in Cetus for brief periods of time.

ECLIPTIC
The ecliptic is the plane defined by the Earth's orbit around the Sun; conversely, in the course of a year, the sun traces a path in the sky along the ecliptic.

ecliptic - (n.)
The plane of the earth's orbit about the sun, which is approximately the plane of the solar system as a whole. The apparent path of the sun across the sky is the projection of the ecliptic onto the celestial sphere.
An ecliptical star, such as Regulus, has a much shorter occultation series than a star hovering near the northern or southern regions of the Moon's orbit, yet an occultation series for an ecliptical star happens twice as often.
The ecliptic is important observationally, because the planets, the Sun (by definition), and the Moon are always found near the ecliptic.
The ecliptic and celestial equator intersect in the constellations of Pisces and Virgo. The intersection isn't just some astronomical abstraction. It defines the seasons, because the Sun reaches the intersection points at the time of the equinoxes.
The ecliptic can refer to many slightly different ideas which all relate to the Earth's orbit. The plane in which the Earth goes around the Sun is called the ecliptic.

The second reason is that because the ecliptic is inclined by 23.5 degrees to the celestial equator a significant part of the suns motion around the time of the equinoxes is in a north-south direction and less in an east-west direction as compared ...

We have to have it ending up as a solar system like we see today, with all the planets spread out around the Sun in the ecliptic. How can we do that? One thing that will help the process is to have the nebula rotating a little bit. What good is that?
