Four-and-a-half billion years ago, our planet suffered the nearest miss imaginable. Theia, a rogue planet the size of Mars, crashed into an infant Earth. Earth itself survived, but nothing was the same ever since. Tectonic plates form. Earth has a fairly large moon, the largest in relation to the parent of the entire solar system. The crash of Theia had created the moon and tipped Earth to the extent of having seasons.
To that end, for the existence of an alternate Earth with a vertical axial tilt--an axial tilt that discourages the development of seasons--how different would the moon have to be, in regards to origin, orbital trajectory, geology, chemistry, etc.?
