Tonight, July 20, that bright “star” near the moon is no star. It is Jupiter.
Jupiter is shining more brightly than any star now (though Mars is even brighter). The moon and Jupiter are particularly close tonight and during this weekend.
Venus and Mars are the other starlike objects that outshine Jupiter in the evening sky, but you can tell the difference. Venus is in the western sky as darkness falls. Mars is in the southeast horizon at nightfall. Jupiter will be near the moon for this weekend.
