On Monday night time, December 21, Jupiter and Saturn will look nearer collectively than they’ve appeared since March 4, 1226, virtually 800 years in the past. This occasion, happening on the December solstice, is called a “nice conjunction.”
“On the night of closest method on Dec 21 they’ll seem like a double planet, separated by just one/fifth the diameter of the total moon,” says Rice College astronomy professor Patrick Hartigan.
From Rice University:
Although the very best viewing circumstances shall be close to the equator, the occasion shall be observable anyplace on Earth, weather-permitting. Hartigan mentioned the planetary duo will seem low within the western sky for about an hour after sundown every night[…]
Those that choose to attend and see Jupiter and Saturn this shut collectively and better within the night time sky might want to stick round till March 15, 2080, Hartigan mentioned. After that, the pair will not make such an look till someday after the yr 2400.
