A sight you won't see again until 2026

Frigid air is coming in and it will be a chilly inauguration but later this evening, even if the wind picks up and any clouds break up, well worth a quick look outside.  The gibbous moon and the brilliant planet Jupiter will be less than 1° apart tonight. 


  What astronomers call a "conjunction"  Tonight the moon is about 250,000 miles away and Jupiter is about 413 million miles away (almost 2000 times farther away)  yet they will appear to be almost touching in the night sky.


  In fact in parts of the South America the tonight the moon will "occult" the brilliant Jupiter.  Much more about this cosmic event here and here and of course at Sky and Telescope here .Bundle up and enjoy.
