What is the tilt of the earth in the coldest season?
You may be confusing the earth’s “tilt”, which is always about 23.5 degrees relative to the ecliptic, and how the tilt happens to be oriented at any given time. Imagine a coin “heads” side up and the face oriented properly, at the top of a piece of paper. That’s the earth. The sun is at the center. Put your index finger on the coin and move it counter-clockwise around the sun. Wherever the ‘earth’ is, when you take you finger off the coin the face is always oriented the same way– the top of the head is up. The earth’s tilt is something like that. It’s always virtually the same size, but during one part of the orbit the tilt is oriented so that the north is toward the sun, and at the opposite part of the orbit, the tilt is oriented so that the south is toward the sun.
