In World Building I asked a question about the climate of an hypothetical planet.

There Vogon poet said that

Everyone above 10° latitude will be in permanent drought

Considering that there were no Milankovitch cycles (with a year of exactly 31104000 seconds (360 Earth days) and a day of exactly 86400 seconds (24 hours) and a circular orbit with a distance between the surface of Earth and the Sun's surface equal to the harmonic mean of the current distance), Earth was an oblate spheroid (with the same mass) with a perfectly smooth surface (only allowing for moderate variance due to fauna, flora and civilisation), there were only 2 bodies in the universe Earth and a Sun (a perfect ball with smooth surface and uniform density with the same amount of radiation).

What would be the least equatorial bulge consistent with modest amounts of water in polar regions?

  • $\begingroup$ Do you think I should define polar regions like say above (and below) 80° or 85° Latitude (North and South) $\endgroup$ Nov 20, 2022 at 10:38
