Astronomy Info & Events: June

The Visible Planets

Mercury just can’t get out of the dawn’s glow from our latitude and will not be visible for us this month.

Venus is shining brilliantly in our western evening sky after sunset. On June 4, Venus reaches its greatest eastern elongation from the Sun of about 45°. On June 21, the summer solstice, look for a nice grouping of bright Venus with the waxing crescent Moon and the much fainter planet Mars. Venus spends most of the month moving through the faint constellation of Cancer, the crab, before moving into the constellation of Leo, the lion, on June 26.

Mars has been dimming a lot since its opposition back in December of 2022 and is now found in our western sky after sunset. Mars spends the first part of the month moving through the constellation of Cancer, the crab, along with the much brighter planet Venus. It then enters the constellation of Leo, the lion, from June 19 onwards. On June 21, see Mars near the waxing crescent Moon and the much brighter Venus.

Jupiter is found rising along the east-northeast horizon about an hour before sunrise this month. Jupiter is located within the constellation of Aries, the ram, through the month and will remain in this constellation for the rest of the year. Before sunrise on June 14, look for Jupiter just to the right of the very shallow waning crescent Moon.

Saturn rises along the east-southeast horizon at around 2:30 a.m. early in the month and just a little past midnight by the end of the month. Saturn can be found moving through the constellation of Aquarius, the water bearer, where it will remain for the rest of the year.
