Dr Daniel Cunnama, a science engagement astronomer at the South African Astronomical Observatory, confirmed that a spectacular conjunction of Jupiter and Saturn on 21st December will be visible in South Africa. “You can look to the West just after sunset and you will see them over the next two weeks.

 According to the BBC’s Sky at Night magazine, the closest giant planetary “kiss” since 1623 will see gas giant planets Jupiter and Saturn just 0,06° apart.

“Our Solar System’s two gas giant planets have been edging closer in recent months, and on Monday, December 21 Jupiter and Saturn will be less than a degree apart in the night sky,” says the magazine.

The spectacular sight will be visible in clear skies across the world. Sky at Night said Jupiter and  Saturn won’t really be close to each other at all. “In fact, on that date — which also just happens to be the date of the December solstice — Saturn will be about twice as far from Earth as Jupiter will be.

“However, our line of sight from Earth will suggest otherwise, as we all get to witness (clear skies allowing) the closest planetary conjunction of Jupiter and Saturn that most of us are ever going to see. “Saturn and Jupiter appear to pass close to each other, as seen from Earth, every 20 years, and when they do we call it a ‘great conjunction’.”

If you see it, count yourself lucky.
