How to catch the rare rendezvous of Venus and Jupiter

Look to the western horizon just after sunset on Saturday, Aug. 27, and Venus and Jupiter will appear as close together as they will for the next half century, until November 2065.

This type of celestial event is called an “appulse” and occurs when two objects in the sky move so close together – as seen from Earth – that they reach the absolute minimum separation between two celestial objects. The view of this convergence is so dramatic than many speculate it was this type of event that was responsible for the star of Bethlehem as described in the Bible.

To see the two planets appear to converge, head to an area where the horizon is free of trees and buildings. About half an hour after sunset, the two planets will be visible about anywhere from 5 to 20 degrees above the horizon, depending how far south you are. You can estimate 10 degrees of sky by holding your fist out at arm’s length, so look for the planets within two fist-widths above the western horizon. READ MORE.
