Classic SF Featuring Planets With Very Long or Very Short Days | #SciFiSunday

Mission of gravity

Days are still long but getting shorter, with yet another seasonal change on the horizon. It seems like the change in daylight hours is one of those topics we can’t stop discussing year after year. Our obsession with how long the sun is around each day is something SF authors have been tuning into for decades. Check out this fun list from Tor.com.

Earth is blessed with a day neither of extraordinary length nor of extreme brevity. Currently it is about twenty-four hours long. A quick glance at planets like Mercury and Venus shows us that worlds can have days much longer than Earth’s; bodies like Haumea suggest that days could be much shorter.

SF authors have notice this and written books about planets/planetesimals with different day lengths. Consider these five vintage works.
