The sky in September 2016
Summary: Giant planet Jupiter disappears from view this month while brilliant Venus stays low above the western horizon after sunset. Here are our tips on observing Venus. Mercury may be seen at the end of the month in the morning sky if you have a good horizon.
Mars and Saturn are still close together in the early evening sky, near the bright red star Antares, whose name actually means “rival of Mars”. From 2-21 September, both are in the “forgotten” zodiacal constellation of Ophiuchus, the serpent bearer.
The Moon always makes a great target for a small telescope, which come into view as its phases change. We’ve a guide to where to find 50 of the best lunar features, plus a checklist to download so you can tick them off as you spot them!
