Ecliptic
황도 · The Sun's apparent yearly path
The *path the Sun appears to trace* across the celestial sphere over a year. As Earth orbits the Sun, the Sun appears to drift through the stars from our point of view.
Obliquityε ≈ 23.44°
The tilt between the ecliptic and the celestial equator — what gives Earth its seasons.
Four cardinal points
Vernal equinoxα=0h, δ=0° · around March 21 · day = night
Summer solsticeα=6h, δ=+23.44° · around June 22 · longest day
Autumnal equinoxα=12h, δ=0° · around September 23
Winter solsticeα=18h, δ=−23.44° · around December 22 · longest night

★ Sun (Sol)Today's position · —
On this map, Sol marks *where the Sun stands among the stars today*. It drifts one tiny step along the ecliptic each day, tracing a full loop over a year.
☾ EarthToday's position (antisolar point) · —
Astronomically, *Earth is not a star on the celestial sphere*. On this map, Earth marks the *midnight zenith* (antisolar point) — the patch of sky where the full Moon and prime stargazing live. It always sits opposite the Sun along the ecliptic.
