Tonight is a good opportunity to see Venus very close to M45, the Pleiades open star cluster, in the west after sunset. The pair are actually closest tomorrow, but due to time zone differences, observers in the northern hemisphere will see the pair at their closest tonight. Keep an eye on Venus over the next few nights to see how it moves and slowly passes the distant star cluster.
