Ecliptic & Zodiac Band
This interactive simulator explores Ecliptic & Zodiac Band in Astronomy & The Sky. Celestial equator vs ecliptic, obliquity, Sun on the yearly path (symbols as map, not astrology). Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Suited to beginners and first exposure to the topic. Typical context: Astronomy & The Sky.

How it works
Earth’s spin axis is tilted relative to the orbital plane. The ecliptic is the intersection of that plane with the celestial sphere; the celestial equator is the projection of Earth’s equator. The Sun appears to travel along the ecliptic once per year.
