Thought experiment: Where would the 'ecliptic equator' be?

Factual Questions
1

That is, if we had a word for the imaginary line where Earth intersects the ecliptic, what countries would it go thru?

2

The Tropics? we already have a word for those.

3

The countries would change as the Earth rotates. Any point between the Tropic of Cancer and the Tropic of Capricorn will pass through your imaginary line twice per day.

4

This is a nice map showing the current position of the sun and moon over the earth:

Thanks, I can see that now.

The orbital plane of the Earth is also inclined about 1° to the invariant plane of the solar system, so the other planets and indeed the rest of the universe appears to bob up and down a bit relative to the ecliptic plane, separate from the 23.4° axial tilt.
