In a rare celestial event, Jupiter and Saturn will be seen very close to each other (conjunction) on 21st December 2020, appearing like one bright star.
Key takeaways
Conjunction occurs when two celestial bodies visually appear close to each other from Earth.
Astronomers use the term great conjunction to describe meetings of the two biggest worlds in the solar system, Jupiter and Saturn.
It happens about every 20 years.
The conjunction is the result of the orbital paths of Jupiter and Saturn coming into line, as viewed from Earth.
Jupiter orbits the sun about every 12 years, and Saturn about every 29 years.
It will be the closest alignment of Saturn and Jupiter since 1623, in terms of distance.
The next time the planets will be this close is 2080.
They will appear to be close together, however, they will be more than 400 million miles apart.
