On the celestial sphere there is a line that goes all the way round, called the ecliptic. It is the apparent path of the Sun against the background stars, as the Earth revolves in its orbit. The ecliptic is not the same as the equator (the two planes are inclined by 23½ degrees) but it crosses the equator at two points.
The ecliptic defines the plane of the Earth's orbit, because actually the Sun stays where it is while the Earth revolves.
The other planets' orbits are almost exactly in the same plane as the Earth's, which means that all the planets stay close to the ecliptic all the time.
So a planet's position is pretty well defined by its longitude on the ecliptic, measured from a special point called the First Point of Aries, which is where the Sun is at the Spring Equinox. It is a direction defined by the intersection of two planes, the Earth's equator and the ecliptic.
Unfortunately this fixed direction, which is used as the basis of the geocentric spherical-coordinate system (right-ascension and declination), is not itself actually fixed, but it moves right round the ecliptic every 25,000 years, so star atlases have to be redrawn and republished every 50-100 years.

What is a cosmic repetition?
Cosmic repetition refers to patterns or cycles that occur in nature or the universe, such as the changing of seasons, the phases of the moon, or the orbits of planets. These repetitions are integral to the structure and harmony of the cosmos.
What sphere do volcanoes occur in?
geosphere
What celestial event occur around July 4th?
aphelion
Which sphere does condensation mostly occur?
atmosphere
What does the ecliptic refers to?
The ecliptic is the plane in which the orbit of the Earth around the Sun lies .It is almost but not quite the same plane as the other planets (each planet has a slightly different tilt but the differences are less than 1 degree)
In which sphere does condensation occur?
In K12 it's Atmosphere
Which sphere does condensation occur?
In K12 it's Atmosphere
What are the changes that occur as a comet orbits the sun?
it gets a tail
What is ecliptic in relationship to the sun and the earth?
Ecliptic means the imaginary line that marks the path the Sun moves on annually. The ecliptic path projects the Earth's orbit and along helps mark when eclipses will occur.
Is there evidence of volcanic activity on Saturn and Uranus?
Volcanism occurs on planets with a liquid metal layer beneath a solid rock layer. Saturn and Uranus are gas giants and have neither, being completely composed of gas. Therefore, no volcanism can occur on those planets or Neptune or Jupiter for that matter. They can occur on the moons, however, under the right circumstances. Io, a moon of Jupiter, experiences the most volcanism of any celestial body in the solar system.
In what sphere do the northern lights occur?
The Northern Lights occur in the northern hemisphere, in the ionosphere, the highest level of the atmosphere.
Do lunar eclipses occur on other planets?
Yes.
