The Visible Planets
Mercury is not visible this month from our latitude. Mercury will be at inferior conjunction (in between the Sun and the Earth) on October 25.
Venus continues to shine brightly in the eastern sky before sunrise. On October 1, 2 and 3 you can find Venus near the bright star Regulus of the constellation of Leo, the lion. By the end of the month you can see Venus sinking lower in the sky, moving towards the glare of the rising Sun.
Mars reigns supreme this month within the constellation of Pisces, the fish, even outshining the king of the planets Jupiter in our evening sky. It rises in the east at sunset and sets in the west by sunrise, providing glorious views of this planet all night long. As Mars is at its closest to the Earth on October 5/6, the dates around this time marks the best time this year to view this incredible world through a telescope. The polar caps and distinctive light and dark features across the disc of Mars should be visible. Look for bright reddish coloured Mars above the Moon on the nights of October 2/3 and again on October 28/29. Mars is at its point of opposition on October 13. You will not see Mars this close to Earth again until the year 2033! A special week of viewing from the RASC Observatory at TWOSE is being planned for the two weeks surrounding the close approach.
Jupiter is found shining brightly low in the southern sky at sunset. It is found in the constellation of Sagittarius, the archer, and is just above and to the east of the asterism of the “teapot”. Jupiter continues to move westward and then sets about 3 hours after sunset in the southwest.
Saturn is seen in southern sky at sunset, setting in the southwest about three hours later. It’s located in the constellation of Sagittarius, the archer, and is seen just to the east of the much brighter Jupiter. On October 22 look for a nice conjunction between Saturn, Jupiter and the waxing crescent Moon. Saturn continues to be one of the highlights of early evening observing at the RASC Observatory into the fall/winter period.
