The story tells that the three wise men, Melchior, Gaspar and Baltasar, followed the star of Bethlehem to find Jesus in his place of birth.
Although it has been said that this only occurs every 800 years, The National Aeronautics and Space Administration of the United States (NASA) pointed out that this type of event occurs every 20 years. However, this one is special, because it is a particularly large conjunction and will not be seen for another 60 years.

From Earth, Jupiter and Saturn will look so close that they will appear like a ‘double planet’ system, as reported by Nasa.
According to that entity, both planets have been traveling together in the sky during this year. Only in December they will get close enough to produce a beautiful astronomical spectacle.
How to see it?
NASA points out that in the first three weeks of December it has been possible to observe the journey that the two planets have made. But nevertheless, reported that the day that will be seen more clearly is next December 21.
On that date the two huge planets will only be one tenth of a degree apart. That is, from our perspective they will be at a distance similar to the thickness of a coin, NASA warned.Both will be visible next to their moons and will be so close that Saturn can appear like a satellite of Jupiter.
