On the 23rd, the “ice giant” Uranus will be visible all night, as it rises when the sun sets (hence it is opposite the sun). It will also be at its largest for the year: a diminutive 3.73″ of arc. Due to its distance and close-to-circular orbit, Uranus doesn’t vary that much in brightness over time. It will reach magnitude 5.7 from mid-October through early November before slightly fading to magnitude 5.9 in late March 2019. This makes it a naked-eye target in dark skies and easy to locate in a binocular or finderscope.
About every 26-months, Earth and Mars get a good look at each other as their orbits cause them to line up together on the same side of the Sun. At the instant that Earth is between Mars and the Sun we have “Mars Opposition” — Mars is opposite the Sun in Earth’s sky. Mars is closest to Earth around this time and amateur astronomers make a point of observing it.
Saturn will be visible all night in the sky on the 15th as it rises when the sun sets (hence it is opposite the sun). Now is a good time to revisit an essay I wrote a while back about this visually appealing planet.
It’s Saturnday
I’ve found that first-time views of Saturn through a telescope typically elicit gasps of delight followed by inquisitive questioning.
Saturn’s startling beauty can open the door to wonders and knowledge about the universe that can inspire a love and appreciation of all the arts, sciences, and history.
Understanding something of the vastness and nature of the universe and our unique position as the only species possessing such knowledge suggests we commit to fostering the best in us: love, kindness, respect for learning and for all the amazing life-forms we’re so fortunate to share on this wonderful planet.
So let’s use Saturn as a means to enrich our future and help preserve our earthly paradise.
Spread the word to change Saturday to Saturnday through all media and contacts, in every social venue, to start dialogues that can open the minds and hearts of our earthling friends. Â Caring for our precious planet and it’s lucky inhabitants, will make future generations proud of our time here.
