The Bible says that a star led the Magi from the East and indicated the place where one could find the Baby Jesus.
There are many theories that attempt to explain this miracle among them is that it was the bright planet Venus, the passage of comets Halley or Hale-Bopp, a concealment of the Moon ..
One hypothesis is supported by the astronomer Johannes Kepler, who in 1606 said the star was a rare triple conjunction of the Earth with the planets Jupiter and Saturn, passing by the Sun and at the same time by Fish. This combination is presented to the observer on Earth as a very bright star. Another assumption, this latest idea is a new bright star seen near the star Theta Aquilae.
The star of Bethlehem is remembered placing it both in the representation of the manger as the tip of the Christmas tree.
