Imagine Earth had an axis tilted by 16 degrees instead of 23. What would the gap in latitude be between its Arctic Circle and its Tropic of Cancer?

1. The Tropic of Cancer sits at the latitude that matches the tilt itself. 2. With a 16 degree tilt it would lie at 16 degrees north. 3. The Arctic Circle sits at 90 degrees minus the tilt. 4. That gives 90 degrees minus 16 degrees, which is 74 degrees north. 5. The gap is 74 degrees minus 16 degrees, which is 58 degrees. 6. Answering 74 degrees stops at the Arctic Circle and forgets to subtract the tropic. 7. Answering 16 degrees quotes the tilt itself, which is only one of the two latitudes. 8. Answering 39 degrees adds the two latitudes in the wrong direction. _Source: OpenStax Astronomy (CC BY 4.0), Ch 4 "Earth, Moon, and Sky" and Ch 5 "Radiation and Spectra", section 4.2 The Seasons_
