this is my favourite random factoid about mercury. on most planets the sun moves from east to west, then venus decides to be different and has the sun move from west to east, and then mercury comes along and says “¿porque no los dos?” and makes the sun do a whole reverse parking manoeuvre and then carry on like it was nothing.
i should probably mention that this happens over the course of about 8 earth days and there’s no atmosphere for the sun to light up orange, so it would probably also be the most boring sunset in the solar system, but somehow i don’t think sedna would mind.
