  • $\begingroup$ The question is based on several misconceptions. Deserts are not really the result of axial tilt: they're the result of circulation patterns and geographic barriers. For instance, a lot of desert is immediately downwind of mountain ranges. ("Rain shadow") Likewise, not all deserts are hot: the US Great Basin and the deserts of Central Asia are in temperate regions. Antarctica is also a desert. $\endgroup$

  • $\begingroup$ desert does not mean hot, many deserts are cold, desert refers to the amount of precipitation. $\endgroup$

  • $\begingroup$ That’s not what’s being asked. I suggest rereading the question. The tilt of the planet mainly serves to freeze water at the poles to get a dry and arid equator. I edited the question to get rid of the misleading parts. If you have further criticism feel free to edit the question. $\endgroup$

  • $\begingroup$ The problem is that things just don't work the way you seem to be assuming they do. To get maximal freezing at the poles, you'd want 0 tilt, to eliminate seasonal thaws. But the only way to get an actual desert planet (rather than a planet with occasional deserts, like Earth) is to have much less water in the first place: something like Mars, but with higher gravity to hold an atmosphere. $\endgroup$

  • $\begingroup$ @jamesqf You just missed a good opportunity to answer the question. $\endgroup$
