Friday, April 15th.  The sun rises at 6:58.  It’ll be up for 13 hours and 28 minutes, setting at 8:27.   The moon, 2 days before full, will set at 5:41 tomorrow morning.

If you’ve notices that the names we use for features on the moon sound familiar when used in other contexts, you’re right.  Lunar craters are named for astronomers, scientists, philosophers and explorers.  The mountains on the moon are named for earthly mountain ranges.  The great lava plains, misnames seas are given fanciful names like the Sea of Tranquility, which I usually leave in the original Latin.  In this case Mare Tranquilitatis.  The naming convention for craters pretty much holds for the other bodies of the solar system.  The next bodies to get crater names will be Mercury, which the MESSENGER spacecraft went into orbit of last month and the asteroid Vesta, which the Dawn spacecraft will reach in July.

* Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.
