Venus is not visible because it will be
too close to the Sun. By the second
week of September this deadly world
will be an ‘evening star’ very low in
the west after sunset. By then, if you
have a pair of binoculars you’ll be
able to see Mercury close to brighter
Venus, but you must wait until the
Sun has set to protect your eyes.
