The Equator is perpendicular to the Earth's Axis of Rotation. The Earth spins on its Axis of Rotation once a day, with this Axis tilted 66½° with respect to the Ecliptic. As a result, the Equator is tilted 23½°. ... In the illustration below, note that the Celestial Equator intersects the Ecliptic at two points.

Since the ecliptic is tilted 23.5 degrees with respect to the celestial equator, the Sun's maximum angular distance from the celestial equator is 23.5 degrees. This happens at the solstices.

Ecliptic: apparent path of the sun around the celestial sphere due to the orbital motion of the Earth. The ecliptic is tilted with respect to the celestial equator due to the Earth being tilted on its axis.

The ecliptic is tilted with respect to the celestial equator. This is due to the fact that the Earth's axis is tilted 23.5° with respect to the plane of its orbit. From the perspective of a stationary Earth, it would appear that the ecliptic is tilted 23.5° with respect to the projection of the Earth's equator.

The ecliptic is shown as a tilted yellowish-green circle. The ecliptic is tilted with respect to the celestial equator by 23.5 degrees which is the tilt of the Earth's orbit that represents itself by this effect.

If the Earth were not tilted, every day would be an equinox and there would be no seasons. However, the path of the Sun against the background of fixed stars (the "ecliptic") is tilted with respect to the celestial equator and intersects the celestial equator in only two points (the equinox positions).

Ecliptic - Topic:Astronomy - Online Encyclopedia ... Ecliptic tilted by 23.5° with respect to the celestial equator. Sun's declination ranges between -23.5° and +23.5°. Vernal equinox right ascension = 0 hours; declination = 0°; Sun rises at 90deg;

What is the celestial sphere? Make sure you know the specific features (north celestial pole, south celestial pole, celestial equator, ecliptic). Why is the ecliptic tilted with respect to the celestial equator? Why is it easier to see the Milky Way in the Southern hemisphere?

Expressed in another way, the ecliptic (path of the sun in the sky) is tilted to the plane of the celestial equator by 23 ½°. This causes the sun to not only move eastward as the earth revolves around this star, but to also move northward or southward with respect to the celestial equator.
