This evening, just after sunset, seven planets — Saturn, Mercury, Neptune, Venus, Uranus, Jupiter, and Mars — will align in the sky. This is an extremely rare planetary alignment and the next time this happens will be in 2040.
Jupiter and Saturn
Today, between 17.30 and 19.00 (Central European time) we can watch solar system’s two largest planets (Jupiter and Saturn) side by side in night sky. It will be the closest ‘great conjunction’ since 1623 and it will be 2080 before the planets align so closely again.
