This Saturday night, make plans to get a clear view of the western horizon in order to see a celestial event that won't happen again until 2065.
Shortly after sunset, Venus and Jupiter will get so close to one another in the sky that, from some locations, they will appear to almost touch. At their closest approach, the two planets will be separated by less than one-eighth the width of the full moon.
If you plan to watch the event, make sure you have a clear view of the western horizon. The planetary pair will become visible about 30 minutes after sunset, positioned about 5 degrees above the horizon.

Handy to know.
