Great Conjunction 2020 | Jupiter and Saturn near alignment with Earth | Sky Map.
You will get an idea of tomorrow's Dec 21, 2020 event.
The orbital paths of Jupiter and Saturn ensure great conjunctions every 20 years.
It was impossible to see with the naked eye, because they happened during the daytime.
The planets will get so close together that they may look like one very bright star.
It will be 2080 before the planets align so closely again.
Great conjunctions happen when Jupiter and Saturn come into near alignment with the Earth.
This year, the planets will appear in the sky one-fifth of the width of a full moon apart.
The event coincides with the winter solstice, when the tilt of the northern hemisphere away from the sun produces the shortest day and the longest night.
