Visible Planets

The Visible Planets

Mercury is not visible this month and will be at inferior conjunction (in-between the Sun and the Earth) on July 21.

Venus is not visible this month and will return to our evening sky in September.

Mars disappears in the glare of the setting Sun in early July and hence will not be visible this month.

Jupiter is the brilliant object located in the constellation of Serpens Cauda (part of Ophiuchus), the tail of the serpent, and is seen low in the south-southeast sky after sunset. Before sunrise, Jupiter will be seen setting along the south-southwestern horizon. During the evening of July 13, look for the waxing gibbous Moon above the bright planet. Jupiter will be one of the highlights of evening observing at the RASC Observatory.

Saturn rises at around sunset along the southeastern horizon and is located in the constellation of Sagittarius, the archer. Saturn reaches its point of opposition on July 9 and is about 75 light minutes away from the Earth. By morning, before sunrise, Saturn gets ready to set below the southwestern horizon. The waxing gibbous Moon can be seen very near Saturn through the evening hours of July 15/16. Saturn will also be one of the highlights of evening observing at the RASC Observatory this summer.
