It is a rare and amazing opportunity to be able to see all five of these bright planets in the sky simultaneously. They will also be in the correct order outward from the Sun, starting with Mercury, Venus, Mars, Jupiter and ending with Saturn. The event last occurred in December 2004, but it was only visible in certain tropical areas.
You can see the Northern Sky as viewed at 5 am in London or you can see the Southern Sky as viewed at 7 am in Brisbane and zoom in to see the locations of Mercury, Venus, Mars, Jupiter and Saturn as they align in the true astronomical locations for the Zodiac.
The display will be visible until early July, so unless you experience an unbelievable string of bad weather, you should be able to view the amazing display. Light pollution is a potential, although likely minor issue. The best conditions are clear, dark skies but luckily, these are all bright, naked-eye objects so you should be able to see the line-up even from the city.
If you have a pair of binoculars or a telescope, point them at the planets and moon (but never the sun). With even a small telescope, or binoculars on a tripod, you can see Jupiter’s largest 4 moons and Saturn’s rings. If you are in a dark enough location with a small telescope, you might also be able to see the atmospheric bands in Jupiter’s atmosphere.
