The Visible Planets

Mercury is visible with difficulty low in the east-northeast sky before sunrise from around August 2 to August 23. It reaches greatest elongation west (19 degrees west of the Sun) on August 9.

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

Mars is too close to the Sun to be seen 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 as the bright object low in the southern sky after sunset. During the evening of August 9, look for the waxing gibbous Moon above and to the east of the bright planet. Jupiter will be one of the highlights of evening observing at the RASC Observatory this summer.

Saturn now rises before sunset along the southeastern horizon and is located in the constellation of Sagittarius, the archer. The waxing gibbous Moon can be seen very near Saturn through the evening hours of August 12/13. Saturn will also be one of the highlights of evening observing at the RASC Observatory this summer.
