Cosmic Xmas Reunion: Jupiter and Saturn to Appear as ‘Double Planet’ for 1st Time Since Middle Ages


Although the two planets come in alignment relatively frequently – every 20 years or so – the last time the gas giants were this close to each other was when Genghis Khan was still alive.

The two biggest planets in our Solar System – Jupiter and Saturn – will appear so close in the sky on the 21 December winter solstice that they will look like “a double planet”.

Rice University astronomer Patrick Hartigan said in a statement that the two planets align roughly every 20 years, but their current conjunction is exceptionally rare – they haven’t been in such close proximity to each other since 4 March 1226.

The rare phenomenon can be observed from anywhere on our planet if weather permits, according to the scientist.

Despite their unique pre-Christmas bonding, which is observable from the Earth as their convergence, the two planets, in fact, remain hundreds of millions of miles apart.
