things you just didn't know...

if you were to somehow stand on the planet mercury (daytime surface temperature 662 degrees F...) watching a sunset occurring at perihelion (when it's closest to the sun), the sun would not simply set. it would dip below the western horizon and then come back up, only to set a second time, a day or two later.

a day on mercury is about 3 months long for us on earth.

update: oops! i meant two months. it takes 58 days to spin on its axis (you'd think i'd check this...) a year on mercury is about 3 months (88 days to go around the sun).

nighttime temperature is a cozy -274 degrees F... also lasting 3 months.
