Celestial equator is Earth's equator zoomed, in its plane, as the equator (great circle ) of the celestial sphere. The line of intersection of this plane and ecliptic contains a diameter of Earth...

Celestial equator is the zooming of our equator in its plane onto the virtual celestial sphere; it is meaningful to identify the plane of celestial equator as the plane of Earth's equator. Of course, the rotating and tilted Earth's equator transits the ecliptic, at the eds of a diameter, but the celestial sphere is virtual and has an undefined radius.
