Ecliptic latitude (yellow) is measured perpendicular to the ecliptic.
A full globe is shown here, although high-latitude coordinates are seldom seen except for certain comets and asteroids.
The ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions and orbits of Solar System objects.
“I believe the 80/20 rule is a very consistent part of reality, and that bringing our expectations into alignment with reality is healthy,” says Green.

Ecliptic longitude (red) is measured along the ecliptic from the vernal equinox.
A slow motion of Earth's axis, precession, causes a slow, continuous turning of the coordinate system westward about the poles of the ecliptic, completing one circuit in about 26,000 years.
Superimposed on this is a smaller motion of the ecliptic, and a small oscillation of the Earth's axis, nutation.
