Bob Moler's Ephemeris Blog

Merry Christmas! This is Ephemeris for Christmas Day, Monday, December 25th. Today the Sun will be up for 8 hours and 48 minutes, setting at 5:07, and it will rise tomorrow at 8:18. The Moon, 1 day before full, will set at 8:25 tomorrow morning.

The real star of Bethlehem is probably not what is popularly depicted as a bright star in the sky, rather it was something subtle, only noticed by some astrologers. However, gracing our skies tonight we do have, in the morning and again in the evening, two bright star-like objects. I call them star-like objects because they’re planets. In the morning we have brilliant Venus off in the southeast at 7:30 in the morning, and early in the evening we have bright Jupiter in the south. Jupiter is bright enough that when Venus is not in the sky it is sometimes mistaken for it, although Venus would never be seen in the south* in the evening, it’s always too close to the Sun. Again have a Merry Christmas!

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EST, UT –5 hours). They may be different for your location.
